摘要： This invention provides a process for producing a crystallized polyester resin molding. The process includes melting and injecting the below-described first or second compound (a) or (b) into a mold and holding the same in the mold, and then conducting cooling to crystallize a polyester resin of a resulting molding without using an inorganic nucleating agent: (a) a first compound of a crystallization-inducing crosslinked polyester resin, in at least a portion of which crosslinked points have been formed with a crosslink forming agent, and a first non-crosslinked polyester resin; or (b) a second compound of a crystallization-inducing master batch, which comprises the crosslinked polyester resin and a second non-crosslinked polyester resin and abundantly contains the crosslinked polyester resin, and the first non-crosslinked polyester resin. According to the present invention, a crystallized polyester resin molding free from impairment of translucency or transparency can be produced without using an inorganic nucleating agent that would produce haze in the molding.

摘要： Described is a coating composition for the formation of a back coat layer in a magnetic recording medium, which comprises carbon black, a binder and a solvent. The binder is composed of an acrylic-polymer-modified polyurethane resin and a vinyl chloride copolymer having at least one type of terminal groups selected from hydroxyl groups, carboxyl groups or tertiary amino groups.
