Abstract

Abstract Printing compositions for producing a heat transferable design on textiles or fabrics. The compositions consist of a thermoflowable polymer and a blocked isocyanate crosslinking agent flowable at temperatures at which the polymer flows. The blocking agent is removable by heating at a temperature at which the polymer flows, thereby producing a crosslinking agent for crosslinking the polymer. The compositions are substantially tack free at ambient temperatures. Also provided are transfers for producing designs on textiles or fabrics, the transfers consisting of a temporary support with a design formed from a composition of the invention.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 71 words
A printing composition for producing a heat transferable design on a textile or fabric, the composition comprising a thermoflowable polymer and a blocked isocyanate crosslinking agent flowable at temperatures at which the polymer flows, the blocking of the agent being removable by heating the agent at a temperature at which the polymer flows to produce a crosslinking agent for crosslinking the polymer, the composition being substantially tack free at ambient temperatures.
Claim 2
Dependent Claim 71 words
A printing composition for producing a heat transferable design on a textile or fabric, the composition comprising a thermoflowable polymer and a blocked isocyanate crosslinking agent flowable at temperatures at which the polymer flows, the blocking of the agent being removable by heating the agent at a temperature at which the polymer flows to produce a crosslinking agent for crosslinking the polymer, the composition being substantially tack free at ambient temperatures.
Claim 3
Dependent Claim 16 words
A composition according to claim 1, wherein the flowable polymer has hydroxy, carboxyl or amino groups.
Claim 4
Dependent Claim 30 words
A composition according to either of the preceding claims, wherein the blocked crosslinking agent has blocked isocyanate groups, and the thermoflowable polymer has groups reactive with said unblocked isocyanate groups.
Claim 5
Dependent Claim 24 words
A composition according to any of the preceding claims, wherein the blocked crosslinking agent is unblocked at a temperature of from 115 to 170°C.
Claim 6
Dependent Claim 16 words
A composition according to any of the preceding claims, which includes a catalyst for the crosslinking.
Claim 7
Dependent Claim 74 words
A transfer for producing a design on a textile or fabric, the transfer comprising a temporary support member, and a heat transferable design thereon, the design being substantially tack free at ambient temperatures and being formed from a printing composition comprising a thermoflowable polymer and a thermoflowable blocked isocyanate crosslinking agent capable of flowing and being unblocked at a temperature at which the polymer flows, the unblocked agent being capable of crosslinking said polymer.
Claim 8
Dependent Claim 74 words
A transfer for producing a design on a textile or fabric, the transfer comprising a temporary support member, and a heat transferable design thereon, the design being substantially tack free at ambient temperatures and being formed from a printing composition comprising a thermoflowable polymer and a thermoflowable blocked isocyanate crosslinking agent capable of flowing and being unblocked at a temperature at which the polymer flows, the unblocked agent being capable of crosslinking said polymer.
Claim 9
Dependent Claim 22 words
A transfer according to claim 5, wherein the design is produced from a composition according to any of claims 2 to 5.
Claim 10
Dependent Claim 21 words
. A transfer according to either of claims 6 or 7, having a release layer with the heat transferable design thereon.
Claim 11
Dependent Claim 26 words
A transfer according to either of claims 6 or 7, where the clear composition according to claims 2 to 5 is applied after the design layer.
Claim 12
Independent Claim 65 words
A method of producing a design on a fabric or textile, the method comprising applying a printing composition according to any of claims 1 to 5 to the fabric or textile and heating the composition so that the polymer and the blocked isocyanate crosslinking agent flow, the blocked crosslinking agent is unblocked, and the polymer and unblocked crosslinking agent react to produce a crosslinked polymer.
Claim 13
Dependent Claim 23 words
A method according to claim 10, wherein the ink composition is applied using a transfer according to any of claims 6 to 9.
