Problems solved by technology

However, in recent years, from the viewpoint of safety, there is a tendency to restrict the use of lead compounds and cadmium compounds, and the use of zinc compounds with high safety and inorganic compounds such as organic acid salts of alkaline earth metals, hydrotalcites, and zeolites are used in combination. become increasingly stable
[0006] However, sufficient stabilizing effects cannot be obtained only with these low-toxicity stabilizers, so in order to improve resistance to light, heat, oxidation, etc., organic phosphite compounds, epoxy compounds, and phenolic antioxidants are used in combination. , benzophenone-based or benzotriazole-based UV absorbers, hindered amine-based light stabilizers and other additives

Embodiment

[0074] Hereinafter, although an Example is shown and the resin composition for printing films of this invention is demonstrated in more detail, this invention is not limited to this.

[0075]According to the following formulation example, the resin composition mixed with each component was kneaded on a roll at 180°C and 30 rpm for 5 minutes, and then pressed at 180°C for 5 minutes to produce a thickness of 1mm and 30×15cm. Tablets were tested for their yellowness. In addition, the yellowness of the tablet after pressing for 30 minutes was also measured under the same conditions. Moreover, the test piece of 5 x 15 cm was produced from this piece, it heated in the Geer oven (Geer oven) of 190 degreeC, and measured the time until blackening, and evaluated thermal stability.

[0076] Moreover, the resin composition which mixed each component was kneaded at 180 degreeC and 30 rpm according to the following formulation example, and the time until sticking was evaluated as grinding ...

Abstract

Provided are a resin composition for printing film and a printing film having excellent colorability, heat resistance, and printability. A resin composition for printing film characterized in containing (A) 0.001-1 part by mass of (a-1) at least one benzotriazole compound represented by general formula (I) and / or (a-2) at least one salicylamide compound represented by general formula (II), (B) 0.001-1 part by mass of β-diketone compound, and (C) 0.001-1 part by mass of phenolic antioxidant per 100 parts by mass of vinyl chloride resin. (In the formula, R1, R2, R3, and R4 each independently represent hydrogen atoms or the like.) (In the formula, R represents a hydrogen atom or the like.)

Description

technical field [0001] The present invention relates to a resin composition for a printing film and a printing film. Specifically, it relates to a resin composition for a printing film capable of forming a printing film excellent in colorability, heat resistance, and printability, and a printing film using the same. Background technique [0002] Printed plastic films are used in a variety of applications such as packaging such as packaging, labels, and toys. However, compared with paper, plastics have less unevenness and fewer voids on the surface, making it difficult to print. In particular, polyolefins and polyesters, which are often used as printing films, have low polarity and poor adhesion to ink. Therefore, corona discharge treatment is used to add unevenness to the surface of the film, or by generating polar carboxyl and hydroxyl groups. to improve printability. [0003] On the other hand, since vinyl chloride-based resins such as vinyl chloride resins have polar gro...
