Abstract:
1. A method of labelling an article comprising the steps of: (a) providing a heat-transfer label having a support portion, and a transfer portion over said support portion for transfer of the transfer portion from the support portion to the article; applying heat to the support portion; placing, upon applying heat, the transfer portion in contact with the article, said transfer portion comprising a single or multiple color design; transferring said transfer portion from said support portion to the article; and providing the design of the transfer portion using a solvent-based phenoxy-epoxy ink; the solvent-based phenoxy-epoxy ink comprising one or more pigments, a blend of solid phenoxy-epoxy resins dissolved in methyl ethyl ketone/toluene combinations combined with a highly monomeric methyl-butyl coetherified melamine formaldehyde resin, and an amine neutralized acid phosphate catalyst in methanol/butanol or an amine neutralized p-toluene sulfonic acid catalyst in methanol for use as a latent heat curable dried coating (ink) that, upon drying and subsequent exposure to temperatures of 375° to 400° F. for less than one minute during the heat transfer process will develop outstanding adhesion, heat resistance, solvent resistance, caustic resistance, and abrasion resistance.
