Tennis ball marking decalcomania

Claim 1

A heat release type decalcomania for application to a section of textile material formed of felted polyamide-containing textile material which is thereafter adapted for vulcanizing to a rubber surface in a mold comprising; (a) a paper-like wax-free flexible temporary carrier strip; (b) a clear film on one surface of said carrier strip formed of a mixture containing a blocked isocyanate stable at room temperature in a mixture containing a polyester, and a silicone modified polyester which when heated to heat release temperature for application of said decalcomania are adapted to react to form a thermoset elastomeric film and effect the release of said clear film from said carrier strip, and said thermoset elastomeric film also having high temperature mold release properties when heated in said mold; and (c) a pigmented thermoplastic elastomeric design fixedly supported by said clear film formed of a first pigmented layer of thermoplastic elastomer which is comprised of a blend of polyamide resins having a softening point of about 100° F. (38° C.) and a second pigmented layer of thermoplastic elastomer superimposed on said first pigmented layer comprised of a blend of polyamide resins having a softening point of about 230° F. (110° C.), said first and second pigmented layers when heated above said softening points during the heating to effect release of said clear film from said carrier strip and during said vulcanizing having a viscosity which enables said layers penetrating deeply into said felted polyamide-containing textile material, and said second layer being non-tacky and resistant to offsetting when placed in contact with said carrier strip at room temperature.
