（従来技術とその問題点）
近年、廃棄物の処理を適性にするため光分解性の樹脂が
フィルム、ブロー成形、射出成形などに使われ始めた。More specifically, the present invention provides a part or all of a photo-degradable molded article or a light- and microbial-degradable molded article with an indicator that changes color when irradiated with light, and determines the level of disintegration of the molded article based on the color change of the index. Concerning how to do this. (Prior art and its problems) In recent years, photodegradable resins have begun to be used in films, blow molding, injection molding, etc. in order to make waste disposal more suitable.

長い時間がかかるケースもある。In the case of photodegradable resin, if it becomes waste and is exposed to sufficient light irradiation, it will become CO2 and H20 due to molecular chain scission, and there will be no problem in waste disposal, but if it is insufficient, it will eventually It is deposited in the soil and does not biodegrade. The same is true when using vinyl ketones or iron compounds as a masterbatch for polyolefins. Furthermore, depending on the application, starch is added to photodegradable resins such as agricultural polyfilms, which are decomposed by both light and microorganisms, but as mentioned above, they do not photodegrade unless they are exposed to sufficient light irradiation. In some cases, parts remain and microbial decomposition takes a very long time.

。The photo-degradable molded product or photo- and microbial-degradable molded product used in the present invention is a cobolymer (hereinafter referred to as ECO) consisting of ethylene and carbon monoxide. It is molded from a blend of ECO and other olefins, or from a polyolefin with a masterbatch of vinyl ketones or iron compounds added. Molding methods include conventionally known inflation, T-die, injection, blow, extrusion coating, and the like.

未満となるとその成形品は脆化したと言われている。Generally, if the elongation of a photo-degradable molded product immediately after molding is 100%, then the molded product is said to have become brittle if the elongation after light irradiation (hereinafter referred to as residual elongation) is less than 5%.
従って、伸び残率が５％未満となるとき成形品に付した
指標が色変化するように色コントロールする。Therefore, the color is controlled so that the indicator attached to the molded product changes color when the residual elongation rate is less than 5%.

つくった成形品。[Claims] 1) A part or all of the photo-degradable molded product or the light- and microbial-degradable molded product is provided with an indicator that changes color when irradiated with light, and the level of disintegration of the molded product is determined based on the color change of the indicator. how to. 2) The photodegradable molded article according to claim 1, wherein the molded article contains a coloring agent whose color change upon irradiation with light is controlled. 3) The photodegradable molded article according to claim 1, wherein the molded article has a mark that controls color change upon irradiation with light. 4) The degree of discoloration due to light irradiation and the degree of photodegradation of a molded article molded from a resin composition consisting of a photodegradable resin and a pigment that discolors when irradiated with light are measured in advance, and a similar correlation between the two is obtained. A method to easily determine the degree of photodegradation of a molded product by measuring and comparing the degree of discoloration of the molded product. 5) Degree of discoloration due to light irradiation of a molded product made from a resin composition obtained by combining a photodegradable resin, a pigment of a specific color that does not easily fade due to light irradiation, and a pigment of a different color that easily fades due to light irradiation. A method to easily determine the degree of photodegradation of a molded product by measuring the degree of discoloration of a similar molded product and comparing the correlation obtained by measuring the degree of photodegradation in advance. 6) A resin molded product containing a pigment that fades or changes color when irradiated with light is pasted or integrally molded onto a part of a molded product made from a photodegradable resin. The degree of discoloration or discoloration of the resin and the degree of photodegradation of the molded product made from the photodegradable resin were measured in advance, and the correlation between the two was determined. By measuring and comparing the degree of fading or discoloration of resin molded parts containing pigments that change color,
A method to easily determine the degree of photodegradation of molded products made from photodegradable resin. 7) A resin molded article containing a pigment that fades or changes color when irradiated with light for use in the method according to claim 6. 8) A paint containing a pigment that fades or changes color when exposed to light is applied to all or part of the surface of a molded article made from a photodegradable resin, and the degree of fading or discoloration of the paint and the degree of color change made from the photodegradable resin are applied. By measuring the degree of fading or discoloration of a molded article coated with a similar paint and comparing the correlation between the two obtained by measuring the degree of photodegradation of a molded article in advance, the degree of fading or discoloration of the paint on a molded article coated with the same paint is compared. A method to easily determine the degree of photodegradation of manufactured molded products. 9) A molded article made from a photodegradable resin whose entire or part of the surface is coated with a paint containing a pigment that fades or changes color when exposed to light.
