ACRYLIC RESIN COMPOSITION, ORGANOSILOXANE RESIN COMPOSITION AND LAMINATES MADE BY USING THEM

摘要

A laminate which is excellent in appearance, adhesion, scratch resistance, abrasion resistance and hot water resistance and has a high level of weatherability and excellent durability, and an acrylic resin composition and an organosiloxane resin composition both of which can be used for the manufacture of the above laminate and have excellent storage stability. The laminate comprises a polycarbonate substrate, a first layer formed on the surface of the polycarbonate substrate, and a second layer formed on the surface of the first layer, wherein the first layer is composed of a crosslinked acrylic copolymer and an ultraviolet light absorber, and the second layer is composed of a crosslinked organosiloxane polymer; and the crosslinked acrylic copolymer comprises specific recurring units and an urethane bond in a specific ratio, and the organosiloxane polymer has a specific structure composed of colloidal silica and alkoxysilanes.
