摘要： A method of production of a plastic laminate having a protective layer on a foamed layer comprising coating plastisol containing a vinyl chloride resin or an acrylic resin having epoxy group and having average particle diameter of 0.05 to 5 mm and plasticizer as the essential components on the surface of vinyl chloride resin layer containing an organic foaming agent, then forming the combined layers by heating and foaming is provided. A plastic laminate having a protective layer of polyvinyl chloride having excellent surface strength, abrasion resistance and resistance to chemicals on a foamed layer can be produced efficiently.

摘要： A crosslinking plastisol comprising (1) an epoxy group-containing vinyl chloride resin, (2) a triazine compound, (3) a plasticizer, and (4) an optional amino group- and/or thiol group-containing silane compound. The plastisol is capable of providing a shaped article or a laminated article, which has good heat distortion resistance, chemical resistance, resistance to whitening due to water, adhesion, transparency and thermal resistance on processing.

摘要： A vinyl chloride resin plastisol can be prepared without the shearing action mixing conventionally required for mixing a resin and plasticizer, merely by immersing in a conventional plasticizer, aggregates in the form of a dry power and having an average diameter of 80 to 700 .mu.m of vinyl chloride resin particles; using a spray drying apparatus to form aggregates having an average diameter in the range from 80 to 700 .mu.m or by adding an organic fluid which is barely soluble in water and does not dissolve or swell the vinyl chloride resin to the aqueous dispersion of the vinyl chloride particles, followed by drying the aggregates thus formed at a temperature of 70.degree. C.or below.
