Embodiment

[0083] As shown in Table 1, 5 transfer coating formulations were tested. Each transfer coating included a multifunctional acrylate to aid in adhesion to the donor substrate. Each transfer coating included 1,6-hexanediol diacrylate to aid adhesion between the transfer coating and the receptor substrate. Transfer coatings include photoinitiators (e.g., RUNTECURE TM 1104) to facilitate curing of the coating under UV exposure. Each formulation was heated in an oven at 60°C for 30 minutes to aid in mixing.

[0084]

[0085]

[0086]The formulations were tested for adhesion, surface resistance (using deionized water according to ASTM D257), transmittance, haze and pencil hardness. Adhesion between the transfer coating and the substrate was determined according to ASTM D3359, where 5B means 100% adhesion to the substrate and OB means 100% delamination of the transfer coating from the substrate. Adhesion was measured before exposure to boiling water, after exposure to boili...

Abstract

An ultraviolet curable transfer coating can comprise: a multifunctional acrylate oligomer; an acrylate monomer; and a photoinitiator; wherein the ultraviolet curable transfer coating includes a total weight, wherein 30 % to 80 % of the total weight comprises the multifunctional acrylate oligomer, wherein 15 % to 65% of the total weight comprises the acrylate monomer, and wherein 3% to 7% of the total weight comprises the photoinitiator.

Description

Background technique [0001] Conductive coatings can be used in various electronic devices. These coatings can provide functions such as EMI shielding and static dissipation. These coatings can be used in many applications including, but not limited to, touch screen displays, wireless electronic panels, photovoltaic devices, conductive fabrics and fibers, organic light emitting diodes, electroluminescent devices, and electrophoretic displays such as electronic paper. [0002] The conductive coating may include a network-like pattern of conductive traces formed from metal. The conductive coating can be applied to the substrate as a wet coating, which can be sintered to form these networks. However, the sintering process may damage some substrate materials. [0003] Accordingly, there is a need in the art for transfer coatings that can provide strong adhesion between conductive coatings and substrates. Contents of the invention [0004] A UV-curable transfer coating compris...
