Abstract
A resin molded product, a laminate, and a decorative sheet having high weatherability. A decorative sheet includes a resin molded product as a protective layer, and the resin molded product includes an ultraviolet absorber having pKa of −5.5 or more and −4.5 or less when irradiated with light, and a photostabilizer having pKa of 3.0 or more and 7.0 or less. The added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the resin.
Claims18
A resin molded product, comprising:
- an olefin resin as a main component;
- an ultraviolet absorber having pKa of −5.5 or more and −4.5 or less when irradiated with light;
- and
- a photostabilizer having pKa of 3.0 or more and 7.0 or less, wherein
- an added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the olefin resin.
A resin molded product, comprising:
- an olefin resin as a main component;
- an ultraviolet absorber;
- and a photostabilizer, wherein a difference between pKa of the ultraviolet absorber when irradiated with light, which is a negative value, and pKa of the photostabilizer, which is a positive value, is in a range of 8.0 or more and 12.0 or less, and
- an added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the olefin resin.
A resin molded product, comprising:
- a resin layer including an olefin resin as a main component, an ultraviolet absorber having pKa of −5.5 or more and −4.5 or less when irradiated with light, and a photostabilizer having pKa of 3.0 or more and 7.0 or less, wherein an added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the olefin resin;
- and
- an acid modified resin layer provided on one surface of the resin layer.
A resin molded product, comprising:
- a resin layer including an olefin resin as a main component, an ultraviolet absorber, and a photostabilizer, wherein
- a difference between pKa of the ultraviolet absorber when irradiated with light, which is a negative value, and pKa of the photostabilizer, which is a positive value, is in a range of 8.0 or more and 12.0 or less, and
- an added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the olefin resin;
- and
- an acid modified resin layer provided on one surface of the resin layer.
A laminate, comprising:
- a plurality of resin layers, wherein a photostabilizer having pKa of 4.0 or more and 7.0 or less is included in a top coat layer which is disposed on an outermost surface of the laminate.
A decorative sheet, comprising:
- a resin molded product including:
- a resin layer including an olefin resin as a main component, an ultraviolet absorber having pKa of −5.5 or more and −4.5 or less when irradiated with light, and a photostabilizer having pKa of 3.0 or more and 7.0 or less, wherein an added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the olefin resin;
- and
- an acid modified resin layer provided on one surface of the resin layer.
A decorative sheet, comprising:
- a resin molded product including:
- a resin layer including an olefin resin as a main component, an ultraviolet absorber, and a photostabilizer, wherein
- a difference between pKa of the ultraviolet absorber when irradiated with light, which is a negative value, and pKa of the photostabilizer, which is a positive value, is in a range of 8.0 or more and 12.0 or less, and
- an added amount of each of the ultraviolet absorber and the photostabilizer is 3.0 parts by mass or less per 100 parts by mass of the olefin resin;
- and
- an acid modified resin layer provided on one surface of the resin layer.
