The laminate of the present invention comprises the pressure-sensitive adhesive film of the present invention, a first organic material substrate, and at least one base material of a second organic material substrate and an inorganic material substrate. The liquid crystal display of the present invention and the laminated glass of the present invention each comprise the laminate of the present invention. The present invention can provide a pressure-sensitive adhesive film excellent in level-difference conformability, bleed performance and recyclability, a laminate comprising the pressure-sensitive adhesive film, and a liquid crystal display and a laminated glass each comprising the laminate.
摘要:
A composition of matter includes a mixture of styrene derivative monomers and methacrylate/acrylate derivative monomers, which have one or more urethane, carbamate, amide, and/or amine functional groups, and initiators, and the compositions are used to achieve composition control of the forming polymer, with the mole fraction of acrylate/methacrylate and styrene moieties in the forming polymer determined preferably by the chemistry and composition of the feeding monomers rather than the viscosity of the monomers.

An adhesive bonding method that includes bonding a handling wafer to a front side surface of a device wafer with an adhesive comprising N-substituted maleimide copolymers. The device wafer may then be thinned from the backside surface of the device wafer while the device wafer is adhesively engaged to the handling wafer. The adhesive can then be removed by laser debonding, wherein the device wafer is separated from the handling wafer.

There is provided a support structure for use with 3D printing of objects from computer-aided designs. The support structures include fine points that contact the down-facing surfaces of the 3D object being printed in order to adequately support the 3D object while also being adapted for easy removal after the 3D print process is complete. The fine points are possible by controlling the operation of the dispenser to provide a precise amount of material in a precise location. The dispenser jumps from a first fine point to a second fine point by retracting the print material after the first fine point is printed and then moving the dispenser vertically relative to the first fine point before the dispenser is moved horizontally to the second fine point.

Composite articles having at least one solid substrate of such diverse nature as glass, leather, cellulosic solids (including wood, paper, cotton and cellulose derivatives), polyamide solids, polyurethane solids, natural rubber solids, synthetic rubber solids, phenolic resin solids, epoxy resin solids, styrene polymer and copolymer solids and the like, bonded to an adhesive body which is anti-blocking (non-tacky) at ambient temperature but is heat activatable at relatively moderate temperature as low as 60* C. to provide excellent bonding upon cooling to ambient temperatures, and which comprises a cyclic ester polymer having recurring units of the formula:
WHEREIN EACH R'' is selected from the class consisting of, individually, hydrogen, alkyl, cycloalkyl, aryl, and chloroalkyl, and, together with the ethylene moiety of the oxyethylene chain of Unit II, a saturated cycloaliphatic hydrocarbon ring having 4 to 8 carbon atoms. Also novel adhesive compositions containing the above-described cyclic ester polymer and vinyl alkyl ethers in the form of solutions, dispersions, powders, films, coatings and granules or pellets. The invention is applicable to adhering a broad range of diverse types of substrates without the necessity of using high temperatures or long setting times or toxic materials. It is also applicable to the production of heat activatable coatings or seals for diverse packaging materials, laminating uses, construction uses, investment molding type castings, and repair uses.

FILM FORMING COMPOSITIONS, WHICH GIVE HARD GLOSSY, WATER-DISPERSIBLE FILMS AND WHICH ARE PARTICULARLY USEFUL FOR COATING OR SATURATING FIBROUS SHEET MATERIAL SUCH AS PAPER AND WOVEN AND NON-WOVEN TEXTILES, ARE PREPARED BY COMPOUNDING (INTIMATELY MIXING), IN SOLUTION, 1 TO 5 PARTS BY WEIGHT OF A WATER-SOLUBLE PHOSPHATE ESTER SURFACTANT WITH 1 PART BY WEIGHT OF AN ALKYL VINYL EITHER POLYMER SELECTED FROM THE GROUP CONSISTING OF HOMOPOLYMERS OF ALKYL VINYL ETHERS IN WHICH THE ALKYL GROUPS, HVE FROM 1 TO 18 ALKYL CARBON ATOMS AND COPOLYMERS OF SUCH ALKYL VINYL ETHERS WITH EACH OTHER OR WITH MALEIC ANHYDRIDE. SUCH COMPOSITIONS WHEN APPLIED TO PAPER AND SIMILAR SHEET MATERIAL AS A COATING CAN SERVE BOTH AS A REMOISTENABLE ADHESIVE AND HEAT SEALABLE ADHESIVE. THEY CAN ALSO BE APPLIED TO PAPER ETC. EITHER AS A COATING OR SATURANT TO DECREASE THE POROSITY OF THE SHEET, INCREASE ITS STIFFNESS OR TENSILE STRENGTH. THE WATER SENSITIIVITY OF THE FILMS PRODUCED BY SUCH COMPSOITIONS MAY BE MODIFIED BY INCORPORATING A WOOD ROSIN ESTER (WHICH MAY BE EITHER HYDROGENATED OR UNHYDROGENATED) OR A HYDROCARBON RESIN IN THE COMPOSITION. VARIOUS OTHER ADDITIVES, SUCH AS PIGMENTS TO INCREASE THE OPACITY OF THE RESULTING FILMS, MAY ALSO BE INCORPORATED IN THE COMPOSITIONS.
