A heat release type decalcomania (10) for marking a tennis ball cover comprising a carrier sheet (11), having on one surface thereof a clear film of thermosetting elastomer (12), formed of a siliconized polyester composition and a blocked isocyanate composition which crosslink when heated at a temperature effecting release of the clear film from the carrier sheet and having on the clear film a composite design formed of a first color layer (13), of a polyamide resin having a softening point of about 100 F (38 C) and a second color layer (14), of a polyamide resin having a softening point of about 230 F (110 C) with both said layers having a low viscosity adapted to penetrate the tennis ball cover when the design is heated to a temperature at which said clear film is released from said carrier strip. |
