A retroreflective article 10 has a body portion 14 and a multitude of cube-corner elements 12 that project from a rear side 20 of the body portion 14. The body portion 14 includes a body layer 18 that contains a light-transmissible polymeric material having an elastic modulus less than 7×108 pascals. The cube-corner elements 12 contain a light transmissible polymeric material having an elastic modulus greater than 16×108 pascals. A retroreflective article of this construction can be highly flexed while maintaining good retroreflective performance.

The steps are as follows: (a) forming a bead-planting film; (b) adding solid hard saturated polyester, unsaturated polyester soft resin, carboxyl End-capped polyolefin resin, solvent A to prepare mixed resin A; (c) add mixed resin B, metal complex dye, and solvent B to the mixer to make colored resin; (d) apply colored resin to the bead-planting film to form colored resin Resin layer; (e) forming a reflective layer on the colored resin layer; (f) taking a curing agent and mixing resin A to prepare an adhesive; (g) coating the adhesive on the reflective layer to obtain an adhesive layer; (h) Combining the adhesive layer with the substrate layer, peeling off the carrier to form a glass bead layer, and making a washing-resistant high-brightness color reflective product. The present invention adopts the above process steps, which can greatly improve the production efficiency, and the prepared high-brightness colored reflective products have the advantages of washing resistance, uniform and bright colors, excellent retroreflective effects, and the like.

The invention relates to the reflecting film manufacturing technique field, in particular to a high-strength reflecting film electrostatic bead-planting technique. Through adopting the static plantingtechnique and temperature control, glass beads can be plunged into an adhesive layer on the planting film, and the plunged depth is one third to half of the microsphere diameter. The technique can solve the problem that the glass bead surface electrification in air current bead distribution, can cause the bead-planting surface to overlap with floating beads in the existing bead-planting technique,thereby greatly improving the density of the glass microsphere and enhancing back reflection performance.
