Abstract: There is provided a decorative sheet having high ink adhesion without using an oil-based ink having a high environmental load. The decorative sheet includes: a base paper; a thermoplastic resin layer provided on one surface side of the base paper; an ink layer provided on the thermoplastic resin layer of opposite to the base paper side and containing a water-based ink and at least one of a xylene diamine-based curing agent, a polycarbodiimide-based curing agent, and an aziridine-based curing agent as a curing agent; and a surface protective layer provided on the opposite surface side to the thermoplastic resin layer of the ink layer. The addition amount of the curing agent in the ink layer is preferably 1 part by mass or more and 30 parts by mass or less based on 100 parts by mass of the water-based ink.

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.
