Abstract: There is provided a resin impregnated decorative paper sheet (2) in which a decorative paper sheet (4) is impregnated with an impregnation resin (5). The decorative paper sheet (4) includes: a base paper sheet (6); a pattern layer (7) provided on a surface (6a) side of the base paper sheet (6); a foamed resin layer (8) formed by a foaming agent arranged on a surface (7a) of the pattern layer (7) or in the pattern layer (7); and a thermosetting resin layer (9) provided on a surface (8a) of the foamed resin layer (8). The thermosetting resin layer (9) contains at least one of an epoxy resin, a casein resin, an acrylic resin, and a urethane resin.

Abstract: There is provided a transfer sheet capable of preventing film cracking in thermocompression transfer. To that end, a base material layer (2), a transfer layer (3) provided on one surface (2a) side of the base material layer (2), and an adhesion layer (4) provided on an opposite surface (3a) side to the base material layer (2) of the transfer layer (3) are included, for example. A resin constituting the transfer layer (3) is an uncured ionizing radiation curable resin. A resin constituting the adhesion layer (4) is a thermosetting resin not containing a component causing the resin to exhibit liquid repellency.

Abstract: There is provided a resin-impregnated decorative paper (2) formed by impregnating a decorative paper (4) with an impregnating resin (5). The decorative paper (4) includes: a base paper (6); a picture pattern layer (7) provided on a surface (6a) side of the base paper (6); a filling layer (8) provided on a surface (7a) of the picture pattern layer (7); and a foamed resin layer (9) provided on a surface (8a) of the filling layer (8). The filling layer (8) contains at least one of an epoxy-based resin, an acrylic-based resin, a urethane-based resin, and a casein-based resin.
