Abstract

PURPOSE:To obtain the titled material capable of preventing deterioration of photographic characteristics due to a pigment for coloring by incorporating at least one kind of the pigment selected from specific dyestuffs to the titled material. CONSTITUTION:The titled material contains at least one kind of pigment selected from the group comprising a chrome yellow pigment, a chrome vermilion pigment, a soluble azo pigment, a quinacridone pigment, an isoindolinone pigment and a lake red 4R pigment. Thus, the titled material has not only a bad effect on the photographic characteristics, but also can reduced said bad effect, even in case that the titled material contains the dyestuff which gives the bad effect. Further, even in case that the materials except the pigment which gives the bad effect, such as a binder and another additives, etc., are contained in the titled material, said bad effect can be reduced in the titled material.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a packaging material for photographic light-sensitive materials, and more particularly to a packaging material for photographic light-sensitive materials having a pigment that does not adversely affect photographic properties.

[Background of the Invention] In order to package and store photographic materials such as film and photographic paper, it is used for packaging including photographic film magazines and cartridges in which photographic materials are stored, as well as wrapping paper for wrapping these materials. The packaging materials used include metal, resin, paper, and laminates of these materials that are painted or printed.

Conventionally, coating agents such as paints and printing inks used for painting and printing on packaging materials have been used for metals, such as paints for metals and printing inks for metals.
A film made of oxidatively polymerized resin was applied to the packaging material through heating and baking.

The same applies to other packaging materials such as paper! i! 1 place was used.

However, in coating agents based on oxidative polymerization type resins that are cured by heating, there are many constituent materials that have an adverse effect on photographic performance, and coating agents that use these constituent materials have a negative effect on photographic performance. Painted or printed packaging materials have the disadvantage that the photographic material may break down during storage or before use.

In addition, these paints and inks contain pigments for coloring, and these pigments often deteriorate photographic performance. For example, even if the same resin is used as a binder, the pigments contained in This phenomenon appears as a phenomenon in which the degree of deterioration of photographic performance differs depending on the condition. In addition, these pigments are often mixed not only into inks and paints, but also into resin molded products, paper, tH fibers, etc. used as packaging materials for photosensitive materials, for the purpose of coloring or imparting light-shielding properties. Similarly, it could become a factor that deteriorates photographic performance.

Under these circumstances, technology was developed in the 1980s to prevent the deterioration of photographic performance by improving the binders of paints and inks.

G3, Japanese Patent Application No. 60-265897, No. 60-265
No. 898, etc., these techniques can prevent deterioration of photographic performance due to binders in paints and inks; If it exists, it will have an adverse effect on the photographic performance of the packaging material for photographic materials as a whole, and its range of use has been limited.

Therefore, when it comes to paints and inks, the effects of their constituent binder components as well as pigment components on photographic performance can be evaluated using Xl! In addition, similar measures were required not only for paints and inks but also for packaging materials for photographic materials such as colored resin products containing pigments.

Conventionally used pigments that are unfavorable in terms of photographic properties include, for example, white pigments such as certain titanium oxides, black pigments such as certain carbon blacks, and red pigments such as certain iron oxides (red iron oxide). However, the effects of pigments commonly used as colorants on photographic performance have not been fully elucidated, nor is the mechanism clear.

Presently, packaging materials for photographic materials are colored, so much so that it can be said that there are almost no products that are not colored.The purpose of this is to display text to indicate product specifications, etc., and to provide light-shielding properties. There is a wide range of coloring, including coloring to enhance aesthetic appearance, and the pigments used for coloring are often used in combination of at least two or more types.For example, printing Patrone trademarks, printing labels and light-shielding paper, printing barrier packaging materials, etc. Almost all disc film protectors, outer boxes, etc. use two or more types of pigments. Under these circumstances, it is necessary to investigate the effects of each of the resins, additives, and other pigments used on photographic performance one by one, which takes a lot of time and money. Ta.

[Object of the Invention] The first object of the present invention is to provide a packaging material for photographic materials having a pigment that does not adversely affect photographic performance. (3) Even if pigments that give An object of the present invention is to provide a packaging material for photographic materials that eliminates the adverse effects of substances that adversely affect performance, such as binders and other additives.
