Abstract
An embossed interior finishing material having superior cigarette mark resistance, said material comprising (A) a base material (B) formed on said base material, a foamed and ultraviolet-cured undercoat layer obtained from a vinyl chloride polymer, a reactive plasticizer, a blowing agent and a light sensitizer, and (C) formed on said undercoat layer, an ultraviolet-cured top coat layer obtained from a vinyl chloride polymer, a reactive plasticizer and a light sensitizer, or (C') formed on said undercoat layer, an ultraviolet-cured top paint layer.
Claims13
A method for producing an embossed interior finishing material having superior cigarette mark resistance, which comprises coating a composition comprising a vinyl chloride polymer, a reactive plasticizer, a blowing agent and a light sensitizer on a base material (A), irradiating ultraviolet light partly onto the coated base material, heating the coated base material to form a foamed undercoat layer (B), coating a composition comprising a vinyl chloride polymer, a reactive plasticizer and a light sensitizing agent on said undercoat layer (B), and then irradiating ultraviolet light onto the resulting laminate to form a top coat layer (C).
A method for producing an embossed interior finishing material having superior cigarette mark resistance, which comprises coating a sol for the formation of an undercoat layer (B) comprising a vinyl chloride polymer, a reactive plasticizer, a blowing agent and a light sensitizer on a base material (A), heating the coating to convert the coating to a semi-gel, partly printing or coating an ink containing an ultraviolet-shielding agent, a paint having an effect of shielding ultraviolet light, an ultraviolet-impervious plastic film, a metal foil, paper, a wooden plate or a cloth on the semi-gel layer, then coating a transparent sheet for the formation of a top coat layer (C) obtained from a vinyl chloride polymer, a reactive plasticizer and a light sensitizer on the printed or coated layer, irradiating ultraviolet light onto the resulting laminate, and heating the laminate to provide a foam.
