Coating sheet for preventing adhesion of advertising material

A coating sheet for preventing adhesion of advertising materials, comprising:

• a flexible sheet made of a synthetic resin;
• a protective layer formed on one of the two surfaces of the sheet to protect the sheet from discoloration and decoloration by ultra-violet rays of sunlight;
• a first coating layer formed on the protective layer and provided with a plurality of small projections;
• a second coating layer formed on the first coating layer as a film on the first coating layer;
• an adhesive layer formed on the opposite side of the flexible sheet for attaching the flexible sheet;
• and
• a release paper layer positioned underside and on the adhesive layer to protect the adhesive layer from being contaminated by foreign materials and losing adhesive strength;
• wherein the first coating layer is substantially formed by coating and drying:
• 25 to 35 parts by weight of urethane resin solution, acrylic resin solution, or epoxy resin solution;
• 10 to 20 parts by weight of Polyethylene (PE) thermoplastic resin beads, phenol resin beads, melamine resin beads, epoxy resin beads, polystyrene resin beads or glass beads;
• 40 to 52 parts by weight of urethane thinner and toluene;
• and
• 2 to 4 parts by weight of curing agent, on the flexible sheet;
• and
• wherein the curing agent is substantially isocyanate TDI (toluene di-isocyanate), MDI urethane synthetic resin, diethylenetriamine (DETA), TET (Tetramethylthiurammonosulfide), acrylic, or epoxy curing agent.
