The present invention provides signage articles and methods of making, wherein the signage articles have adhesion-enhancing surfaces for marking materials. The signage articles include a substrate that includes a noncellulosic organic polymeric surface, preferably, a radiation cured coating disposed on the noncellulosic organic polymeric surface and a marking material disposed thereon. Preferably, the marking material is not substantially removed from the signage article upon wiping the marking material with gasoline for five cycles.

Adhesion-enhancing surfaces for marking materials

A novel release liner is provided which has a release surface comprising a syndiotactic polymer. The release liners of the present invention offer superior release to a wide variety of materials without the application of release agents, have relatively high heat distortion temperatures, and are unaffected by radiation sources used to cure most polymeric compositions. The release liners of the present invention can be microreplicated with a pattern which can be transferred to coatings and other impressionable materials to impart unique physical or optical properties. Thus, a method of producing a patterned article is also provided, as is a method of producing a solid object from a curable composition.

Method for making a microreplicated article using a substrate comprising a syndiotactic vinyl aromatic polymer

An interpenetrating polymer network (IPN) or semi-interpenetrating polymer network (semi-IPN) comprises a first phase which is continuous and comprises a flexible polymer and a second phase which is a fluorescent or nonfluorescent durable dispersed or continuous phase and comprises a dye and a polymer, wherein the polymer enhances durability of the dye. Such networks are particularly useful in fluorescent traffic signs or safety devices or in pavement marking tape or paint.

Enhanced dye durability through controlled dye environment

A novel form construction comprising a substrate (e,g., a form sheet or roll goods) having a digital printable surface portion and a release surface portion, on which release coating surface portion a signage with a pressure-sensitive adhesive can be releasably adhered. A digital printable release coating composition is also provided.
