More Information
Summary:This invention provides printing paper which comprises an aliphatic polyester resin utilizing a plant resource-derived biomass material, is excellent, for example, in traveling stability on a printing machine, material strength, reproduction of dots, print sharpness, and waterfastness and is suitable for use in applications where sheet offset printing is carried out, for example, commercial printing applications such as outdoor posters and maps, catalogs, pamphlets, and menues, and a label using the same. The printing paper is a film formed of an aliphatic polyester resin composition comprising 40 to 90% by weight of an aliphatic polyester resin (a) comprising a binary or higher material of aliphatic diol units represented by formula (I) and aliphatic dicarboxylic acid units represented by formula (II) and 60 to 10% by weight of an inorganic fine powder (b). The film has a Gurley stiffness of 50 to 3,000 mg, a surface area S, per projected area 4,292 μm2, of the film surface of 5,000 to 50,000 μm2, and a convex part volume V, per projected area 4,292 μm2, of the film surface of 2,000 to 20,000 μm3: -O-(CH2)m-O- . . . (I) wherein m is an integer of 2 to 10; and -CO-(CH2)n-CO- . . . (II) wherein n is an integer of 1 to 12.
