摘要:
A water-dispersible organic clay complex in which a quaternary ammonium ion having both an oxypropylene unit and an oxyethylene unit is present in interlamellar space of an expansible phyllosilicate. This complex is excellent in dispersibility in an aqueous medium and generates excellent water resistance of the resulting coated film when used as a rheology control agent for an aqueous coating composition.

Even for encrypted programs, when all modules are decrypted all at once at the time of execution, it is possible to analyze codes stored within a storage area. Therefore, a program execution and decryption method that prevents easy analysis via reverse-engineering is required. In order to solve the aforementioned problem, this invention provides a program complex that allows execution of modules while modules are being decrypted upon execution, even if a program has been started. Thereby, modules cannot be easily analyzed and program tamper resistance can be improved.

A multilayer coating film composition is formed by applying a water-borne base coating composition to an article to be coated, such as an automotive body, applying a clear coating composition thereon, and curing by heating, wherein the water-borne base coating composition comprises an emulsion resin obtained by emulsion polymerization of an α,β-ethylenically unsaturated monomer mixture having an acid value of 3 to 50 and comprising at least 65% by mass of a (meth)acrylate ester whose ester moiety contains one or two carbon atoms, a coloring component comprising an optically coherent flaky pigment, and an acrylic polymer compound having a weight average molecular weight of 400,000 to 1,500,000 and represented by the general formula (1):

A recording apparatus for recording compressed video data has compressed video data generator for generating a compressed video data having a plurality of intra frames each of which has no cross-reference to any other frames, and bidirectional interpolated frames and predictive frames each of which has cross-reference to other frame. In the first cycle operation, address detector detects addresses of the intra frames and stores the detected addresses in a memory. A scan information generator generates, with reference to the stored addresses in the memory, scan information for an independent frame including one or two addresses of advanced intra frames and one or two addresses of previous intra frames. The scan information is inserted to each frame and then recorded on a disk. During the reproduce of the disk, the scan information is detected to have a quick access to the intra frame located near by.

There are provided processes for the preparation of .gamma.-methacryloxypropylsilane compounds which comprise carrying out the reaction of allyl methacrylate with a hydrosilane compound in the presence of a platinum catalyst, while allowing at least one of a hindered phenol compound and an aromatic amine compound to coexist in the reaction system with an alkylamine compound or an amide compound, or with a gas containing molecular oxygen, or with a phenol compound having an aminoalkylene group. By using these processes as provided, gelation of the reaction mixture in the reaction system and during the course of purification thereof by distillation can effectively be avoided, and the desired .gamma.-methacryloxypropylsilane compounds can be obtained in good yield.

Purpose of the present invention is consists in provision of a water-borne metallic color coating composition, a two-coating and one-baking application method therewith, and a multilayered coating film having an excellent flip-flop property thereby, wherein the water-borne metallic color coating composition has superior properties such as coloring property, recoat adhesion, chipping resistance, water-resistant adhesion, and the like. The water-borne metallic color coating composition can provide a coating film having the above-superior properties and an excellent flip-flop property, by a two-coating and one-baking application method, without disturbing the orientation of the luster color pigment(s) therein before/after an application of a clear coating composition and without adversely effecting on the flip-flop property.The present invention provides a water-borne metallic color coating composition comprising a film forming resin, a curing agent and a luster color pigment, wherein the film forming resin comprises an acrylic resin emulsion, which is obtainable by a two-stage emulsion polymerization, and which has an acid value within a range of from 1 to 30 mgKOH/g (as a basis of the solid resin content), a hydroxyl value within a range of from 10 to 150 mgKOH/g (as a basis of the solid resin content), and a particle size within a range of from 20 to 140 nm, and the curing agent is an aqueous dispersion of a hydrophobic melamine resin having a particle size within a range of from to 140 nm.
摘要:
When rotating a recording drum at low speed, air is jetted from air jet ports toward a point of irradiation, in a direction to diffuse a gas generating from an image recording medium upstream with respect to a direction of rotation of a recording drum. An air curtain approximately semicircular about the point of irradiation is formed upstream thereof with respect to the direction of rotation of the recording drum. As a result, the gas can hardly diffuse from the point of irradiation upstream with respect to the direction of rotation of the recording drum. The gas is collected from a gas suction opening. Thus, the gas is reliably prevented from contacting the image recording medium having an image recorded thereon.
