摘要:
The invention provides an alkali-soluble adhesive agent characterized by comprising an alkali-soluble resin that is a reaction product (C) obtained by allowing a polycarboxylic acid and/or a polycarboxylic anhydride having two or more carboxyl groups to react with a reaction product of a compound (A) having at least one epoxy group with a monocarboxylic acid compound (B). Preferably, the alkali-soluble resin is used in combination with a ketone organic solvent, optionally with at least one member selected from the group consisting of a melt viscosity reducing agent, a surface active agent and a plasticizer. The alkali-soluble adhesive agent can be removed by an alkali aqueous solution without recourse to any organic solvent, and is of an environmental protection-conscious type with improvements in adhesion, adhesion strength, coatability, surface smoothness, softening point controllability, melt viscosity controllability and spread controllability.

To provide a corrugated tube and an apparatus for and method of perforating a corrugated tube, which are capable of rapidly discharging water, such as water intruding into the inside and condensation water, to the outside and in which a plurality of communication holes can be positively and efficiently formed respectively in predetermined portions of a peripheral surface of a tube body. For example, a wire harness or the like is inserted into a corrugated tube 10 through a slit 12 formed in a tube body 11 of a tubular shape along a generating line of the tube body, the tube body having larger-diameter portions 20 and smaller-diameter portions 30 which are arranged alternatively along the same axis. Usually, the corrugated tube 10, receiving the wire harness therein, is installed in such a manner that the slit 12 is disposed at a lower side, but there arises the case where the slit 12 can not be disposed at the lower side because of the installation direction and a change of the direction. In such a case, any of communication holes 13 which are formed in that portion of a peripheral surface disposed the remotest from the slit 12, and communicate the inside and outside of the tube body 11 with each other is located at the lower side, so that water intruding into the corrugated tube, condensation water, etc., are discharged.

摘要:
A thermal transfer sheet having a back coating layer excellent in heat-resistance is provided by using a styrene-acrylonitrile copolymer as a resin constituting the back coating layer. A thermal transfer material having an excellent heat-resistance and having a back coating layer having considerable strength is provided by incorporating at least two species of heat-resistant particles having different particle sizes in the back coating layer, since the larger species of particle imparts excellent heat-resistance to the back coating layer, the smaller species of particle enhances the total amount of the fillers, and the larger and smaller species of particles function so as to provide a synergistic effect. A thermal transfer sheet having a back coating layer which is excellent in storability is provided by incorporation an alkylphosphate multi-valent metal salt into the back coating layer, since the thus prepared back coating layer has an excellent heat-resistance, does not contaminate another menber or thermal head without wearing the thermal head, and has an excellent slip property and an excellent dye barrier property.
