METHOD FOR MANUFACTURING SYNTHETIC RESIN SKIN MATERIAL

WIPO Patent Application WO/2019/155692

A1

Provided is a synthetic resin skin material manufacturing method comprising: a step for forming a skin material-forming laminate that has a foundation cloth, an adhesive layer on one surface of the foundation cloth, and a skin layer containing a resin having a softening point of 145°C, in this order; and a step for respectively bringing a back-up roll and an emboss roll having recesses and juts into contact with the foundation cloth side and the skin layer side of the skin material-forming laminate, and performing embossing under a temperature condition in which, when the heating temperature of the emboss roll is defined as A (°C) and the heating temperature of the back-up roll is defined as B (°C), A and B satisfy condition (I) [130°C≤A≤180°C], condition (II) [180°C≤B≤250°C], and condition (III) [softening point of resin contained in skin layer-15°C≤A
