Abstract
Abstract A heat-sensitive transferring recording medium comprises a heat resistant substrate and a heat-sensitive transferring ink layer overlying the heat sensitive substrate, the heat-sensitive transferring ink essentially consisting of (1) a wax of penetration (JIS K 2235) of not higher than 25 (at 25° C.), (2) a resin component composed of both ethylene-vinyl acetate copolymer and aromatic modified terpene resin, and (3) a coloring agent, and the content of the resin component being 10-30% by weight based on the solid matter in the heat-sensitive transferring ink. An overcoat layer may be formed on the heat-sensitive transferring ink layer.

Claim 1
Independent Claim
86 words
A heat-sensitive transferring recording medium which comprises a heat resistant substrate and a heat-sensitive transferring ink layer overlying the heat resistant substrate, the heat-sensitive transferring ink consisting essentially of (1) a wax of penetration (JIS K 2235) of not higher than 25 (at 25° C.), (2) a resin component composed of both ethylene-vinyl acetate copolymer and aromatic modified terpene resin, and (3) a coloring agent, and the content of the resin component being 10-30% by weight based on the solid matter in the heat-sensitive transferring ink.
Claim 2
Dependent Claim
86 words
A heat-sensitive transferring recording medium which comprises a heat resistant substrate and a heat-sensitive transferring ink layer overlying the heat resistant substrate, the heat-sensitive transferring ink consisting essentially of (1) a wax of penetration (JIS K 2235) of not higher than 25 (at 25° C.), (2) a resin component composed of both ethylene-vinyl acetate copolymer and aromatic modified terpene resin, and (3) a coloring agent, and the content of the resin component being 10-30% by weight based on the solid matter in the heat-sensitive transferring ink.
Claim 3
Dependent Claim
51 words
A heat-sensitive transferring recording medium according to Claim 1 in which the heat resistant substrate is a plastic film provided with a heat resistant protective layer, and the heat-sensitive transferring ink layer is formed on a surface of the plastic film opposite to the surface having the heat resistant protective layer.
Claim 4
Dependent Claim
94 words
