Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A decalcomania comprising; a substrate, a release layer bonded to said substrate, a second adhesive film layer bonded to said release layer, a design layer bonded to said second adhesive film layer, and a first adhesive film layer bonded to said design layer, both of said first and second adhesive film layers being temperature sensitive, so that said first adhesive film layer softens and becomes adhesive when heated to a temperature within a first temperature range and said second adhesive film layer softens and becomes adhesive when heated to a temperature within a second temperature range, said first temperature range is from about 100°F to about 110°F said second temperature range is from about 150°F to about 160°F. both said first and second adhesive film layers being substantially non-adhesive outside of said first and second temperature ranges, respectively.
Claim 2
Dependent Claim
138 words
A decalcomania comprising; a substrate, a release layer bonded to said substrate, a second adhesive film layer bonded to said release layer, a design layer bonded to said second adhesive film layer, and a first adhesive film layer bonded to said design layer, both of said first and second adhesive film layers being temperature sensitive, so that said first adhesive film layer softens and becomes adhesive when heated to a temperature within a first temperature range and said second adhesive film layer softens and becomes adhesive when heated to a temperature within a second temperature range, said first temperature range is from about 100°F to about 110°F said second temperature range is from about 150°F to about 160°F. both said first and second adhesive film layers being substantially non-adhesive outside of said first and second temperature ranges, respectively.
