DECORATIVE TIRE AND METHOD FOR PRODUCING SAME

摘要

Provided is a decorative tire in which an ink composition including a colorant is directly applied onto the tire surface in order to improve the degree of flexibility in design. This decorative tire has a decorative printed layer formed on the tire surface, the decorative printed layer being a cured film of an active-energy-ray-curable ink composition including a colorant. The ink composition includes a monofunctional monomer having a glass transition point of −30° C. or lower, and a polyfunctional monomer having a glass transition point of 0° C. or lower. Preferably, the ink composition further includes a monofunctional monomer having an alicyclic structure with a glass transition point between 0-110° C. inclusive. Preferably, a surface protection layer that protects the surface of the decorative printed layer is formed on the surface of the decorative printed layer. Also, preferably, a primer layer is formed between the tire surface and the decorative printed layer.

主权项

1. A decorative tire having a decorative print layer formed on a tire surface, the decorative print layer being a cured film of an active-energy-ray-curable ink composition containing a coloring material,
wherein the active-energy-ray-curable ink composition contains active-energy-ray-polymerizable monomers and an active-energy-ray polymerization initiator, and the ink composition contains, as the active-energy-ray-polymerizable monomers, a monomer A): a monofunctional monomer having a glass transition point of −30° C. or lower, and a monomer B): a polyfunctional monomer having a glass transition point of 0° C. or lower.
