摘要:
The present invention provides a thermally sensitive recording medium that possesses a thermally sensitive color developing layer containing colorless or pale colored basic leuco dye and an organic color developer as main components on a substrate, wherein said thermally sensitive recording medium contains at least one kind of an ultraviolet ray absorbent of aqueous emulsion type polymer composed of an emulsion copolymerized compound of (a) ultraviolet ray absorbing monomer, (b) vinyl compound monomer that can copolymerize with said monomer, (c) hydrophilic monomer and (d) reactive emulsifier.
摘要:
A transparent resin laminate comprising a polycarbonate resin base material, an acrylic resin layer comprising an ultraviolet absorbent coated on at least one surface of said polycarbonate resin base material and a cured layer formed by coating a composition comprising polyorganosiloxane and a silicone-containing polymer ultraviolet absorbent on said acrylic resin layer and then curing, wherein a difference of linear expansion coefficient between said polycarbonate resin base material and said acrylic resin layer and a difference of linear expansion coefficient between said acrylic resin layer and said cured layer are 0/° C. to 5×10−5/° C., respectively and a molded article used the same.
摘要:
A durable light resistance and UV-screening action is imparted to a fibrous article by coating the fibrous article with a polymer comprising units derived from at least one monomer selected from those which are represented by the formulae (1) and (2): ##STR1## wherein R is H or CH.sub.3 and X is --O--, --OCH.sub.2 CH.sub.2 O-- or --OCH.sub.2 CH(CH.sub.3)O--, ##STR2## wherein Y is halogen or CH.sub.3, n is 1 or 2, R.sub.1 is C1-6 hydrocarbyl, m is 1 or 2, R.sub.2 is C1-6 alkylene and R.sub.3 is H or CH.sub.3.
