Abstract
A decorative sheet including a substrate layer, and one or more layers of at least one of a transparent resin layer and a top coat layer provided on one surface of the substrate layer, the one or more layers being provided as a front surface layer, wherein at least one layer of the transparent resin layer and the top coat layer contains a radical scavenger, and the radical scavenger is contained in a form of radical scavenger vesicles, which encapsulate the radical scavenger within an outer membrane.
Claims18
A decorative sheet, comprising:
- a substrate layer, and
- one or more layers of at least one of a transparent resin layer and a top coat layer provided on one surface of the substrate layer, the one or more layers being provided as a front surface layer,
- wherein at least one layer which forms the front surface layer contains radical scavenger liposomes, wherein the radical scavenger liposome comprises a hindered amine-based photostabilizer as the radical scavenger encapsulated within a monolayer outer membrane made of phospholipid, wherein an amount of the radical scavenger liposomes is from 0.2 parts to 5.0 parts by mass per 100 parts per mass of a resin of the top coat layer and/or a resin of the transparent resin layer.
A decorative sheet, comprising:
- a substrate layer, and
- one or more layers of at least one of a transparent resin layer and a top coat layer provided on one surface of the substrate layer, the one or more layers being provided as a front surface layer,
- wherein at least one layer which forms the front surface layer is formed by adding radical scavenger liposomes, wherein the radical scavenger liposome comprises a hindered amine-based photostabilizer as the radical scavenger encapsulated within a monolayer outer membrane made of phospholipid, to a resin constituting the at least one layer which forms the front surface layer, wherein an amount of the radical scavenger liposomes is from 0.2 parts to 5.0 parts by mass per 100 parts per mass of a resin of the top coat layer and/or a resin of the transparent resin layer.
A method for producing a decorative sheet including a substrate layer, one or more layers of at least one of a transparent resin layer and a top coat layer provided on one surface of the substrate layer, the one or more layers being provided as a front surface layer, comprising
- forming at least one layer of the front surface layer by adding radical scavenger liposomes, wherein the radical scavenger liposome comprises a hindered amine-based photostabilizer as the radical scavenger encapsulated within a monolayer outer membrane made of phospholipid, to a resin constituting the at least one layer which forms the front surface layer, wherein an amount of the radical scavenger liposomes is from 0.2 parts to 5.0 parts by mass per 100 parts per mass of a resin of the top coat layer and/or a resin of the transparent resin layer.
