Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
81 words
A process of delayed sending recording which comprises sending a heat-sensitive transferring medium and a receiving paper at different speeds such that the sending speed of the heat-sensitive transferring medium is slower than that of the receiving paper, and the heat-sensitive transferring medium being composed of: (a) a substrate, (b) a heat-melting ink layer which overlays said substrate, and (c) an overcoating layer mainly composed of a resin and/or a wax and overlying the transferring-side surface of the heat-melting ink layer.
Claim 2
Dependent Claim
81 words
A process of delayed sending recording which comprises sending a heat-sensitive transferring medium and a receiving paper at different speeds such that the sending speed of the heat-sensitive transferring medium is slower than that of the receiving paper, and the heat-sensitive transferring medium being composed of: (a) a substrate, (b) a heat-melting ink layer which overlays said substrate, and (c) an overcoating layer mainly composed of a resin and/or a wax and overlying the transferring-side surface of the heat-melting ink layer.
Claim 3
