THERMOPLASTIC, THERMALLY-TRANSFERABLE INK COMPOSITION AND PROCESS |
摘要 |
A thermally transferable ink composition having a 20% elongation temperature of less than about 85 DEG C and an elongation at break of at least about 15% comprising: a) from about 50 to 95% by weight of a thermoplastic polymer selected from the group consisting of polyvinyl chloride and copolymers thereof, b) from about 50 to 5% by weight of a flexibilizer for said thermoplastic polymer that is compatible with said thermoplastic polymer; and c) up to about 40% by weight of a colorant. The ink may be therrnally transferred from a carrier to a receptor at low temperatures with the use of vacuum pressure. The transferred ink aaheres tenaciously to the receptor and is flexble. The invention eliminates the need to prepare articles such as sign faces, particularly flexible sign faces, by painting with ink compositions which contain solvents. |
