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

The invention relates to retroreflective articles such as retroreflective sheeting that comprises a core sheet comprising retroreflective elements and a topcoat wherein the topcoat comprises certain water-borne acrylic polymer(s).

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.

Digital printable and releasable form construction and composition useful thereto

A novel form construction comprising a form sheet 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.

Simplified continuous processes are disclosed for converting standard woven or nonwoven fabric into reflectorized fabric in a continuous fashion and in bulk quantities. These processes are easily capable of achieving reflectivities of well over 100 cd/(lux&middot;m ). In the processes, an extended length of fabric is provided such as by unwinding an input roll of fabric to be reflectorized, and the fabric is passed through a station that applies a coating of binder material to the fabric. The fabric then passes through a station where aluminum-coated beads are applied to the coating of binder material. An etching station removes exposed portions of the aluminum coating from the beads after the binder material is allowed to substantially solidify. End-use materials other than fabrics but suitable for enhancing personal conspicuity can be reflectorized in the same way.
