PROBLEM TO BE SOLVED: To carry out heat adhesion more uniformly in a shorter period of time by allowing a moisture-retaining agent to be contained in a heat adhesive layer for effecting effective adherence in use of an electromagnetic wave heating device. SOLUTION: The recording paper comprises a constitution where, e.g. a sublimate thermal transfer receiving image layer 1 is provided on one surface of a carrier 2, and a heat adhesive layer 3 containing a moisture-retaining agent is formed on the other surface. Since the moisture-retaining agent is contained in the heat adhesive layer 3 and water is heated by electromagnetic wave, water taken in the moisture-retaining agent being a great part of water in the heat adhesive layer 3 is heated. Through the agency of the heat adhesive agent lying near the moisture-retaining agent, heat of heated water is transmitted to the heat adhesive agent without undergoing a great loss, thus performing effective heating of the heat adhesive layer. However, as an extremely much moisture-retaining agent, i.e., water is contained in the heat adhesive layer 3, blocking is likely to take place irrespectively of much water taken in the moisture-retaining agent, on the contrary, the effect becomes little as it is extremely less. |
