Abstract
Abstract A paint transfer composite useful in forming a protective coating on a compound structural component is provided. The composite is preferably vacuum thermoformable and is comprised of an optional carrier liner sequentially covered with continuous layer of an optional clear coating, a pigmented base coating and a heat-activatable adhesive wherein the adhesive has a sufficiently low glass transition temperature and a sufficiently high tensile modulus to resist damage to said adhesive layer on impact. A method of paint transfer using the composite and a method of preparing the composite are also provided.

A composite in accordance with claim 1 wherein the activation temperature of said adhesive is greater than about 100°C.
Claim 7
Dependent Claim
16 words
A composite in accordance with claim 5 wherein said activation temperature is greater than about 150°C.
Claim 8
Dependent Claim
27 words
A composite in accordance with claim 1 wherein said continuous coating of dry paint is comprised of a clear, continuous coating on a dry, pigmented base coating.
Claim 9
Dependent Claim
20 words
A composite in accordance with claim 1 further comprising a carrier liner in contact with said layer of dry paint.
Claim 10
Dependent Claim
14 words
A composite in accordance with claim 8 wherein said carrier liner is vacuum thermoformable.
Claim 11
Dependent Claim
177 words
A method of paint transfer comprising: a) mounting a compound structural component in a vacuum chamber having an opening no smaller in area than the surface of said compound structural component to be painted such that said surface of said compound structural component to be painted communicates therewith. b) sealing said opening of the vacuum chamber which communicates with said surface of the compound structural component with a paint transfer composite article in accordance with claim 1, in a manner such that said heat-activatable adhesive layer communicates with said surface of said compound structural component; c) drawing air from said vacuum chamber and exposing said paint transfer composite to heat sufficiently to allow said composite to vacuum-thermoform onto said surface of said compound structural component but insufficient to activate said heat-activatable adhesive layer; and d) then exposing said heat-activatable adhesive layer to heat sufficient to activate said heat-activatable adhesive layer; and e) allowing said heat-activatable adhesion to cool while maintaining said vacuum used to thermoform said composite until said adhesive layer is cooled below its activation temperature.
