Printing Base Material Having Excellent Weathering Resistance

9:

• A method for the production of a printing base material which can be printed on with a laser printer and which has a total thickness of 90 μm to approximately 300 μm, the method comprising the steps of:
• calendering a polyester nonwoven fabric selected from the group consisting of polyester spunbond nonwoven fabrics having a partial thermal adhesion rate of 10 to 35% and paper-machined polyester staple fiber nonwoven fabrics to obtain a flattened polyester nonwoven fabric having a surface roughness (SMD) of 0.5 μm to 2 μm, a thickness of 40 μm to 300 μm, and a basis weight of 30 g/m2 to 200 g/m2;
• applying a resin solution comprising a toner fixing agent, a UV absorption agent, white fine powder, and an antistatic agent in a solvent onto an entire surface of one side of the obtained polyester nonwoven fabric and thereafter drying the solvent and/or crosslinking the resin to uniformly apply a binder layer serving as a printing surface in an amount of 1.4 g/m2 to 18 g/m2;
• and
• if necessary, arranging a release paper onto a surface of the polyester nonwoven fabric on a side opposite the binder layer via an adhesive layer to make the total thickness 90 μm to approximately 300 μm.
