Abstract
An article and method for marking elastomeric articles, such as tires, floor mats, and the like, includes an elastomeric sheet which is marked with indicia using a solvent based ink which contrasts with the elastomeric sheet. The indicia is cured with a clear thermoset layer such as a polyurethane. This is then applied to an uncured elastomeric article and the elastomeric article is cured. The heat and the pressure of curing causes the elastomeric sheet to bond to the elastomeric article. The indicia remains discernible and is not easily marred or dulled. After curing, the transfer can be further marked by heat transferring indicia in the form of a sublimation dye through the clear polyurethane layer.
Claims5
A method of forming a marked elastomeric article comprising:
- forming indicia on an elastomeric sheet by coating a portion of said sheet with a contrasting solvent based ink;
- coating said indicia with a clear thermoset layer and allowing said thermoset layer to set, thereby providing a protective coating over said indicia prior to bonding said elastomeric sheet to said elastomeric article;
- applying said elastomeric sheet to said elastomeric article and curing said elastomeric article thereby bonding said elastomeric sheet to said elastomeric article.
A method of forming a marked elastomeric article comprising:
- coating an elastomeric sheet with a thermoset layer and allowing said thermoset layer to cure;
- bonding said elastomeric sheet to an elastomeric article by co-curing said elastomeric article and said elastomeric sheet;
- heat transferring indicia onto said elastomeric sheet bonded to said elastomeric article by heat transferring sublimation dye through said thermoset layer onto said elastomeric sheet after said elastomeric sheet has been co-cured with said elastomeric article.
