the second part comprises between 0.1 and 99.9 wt. % of UV-curable polyurethane precursor material, as based on the total weight of said composition.

The invention further pertains to a method for manufacturing a multilayer coating for covering vehicle body parts.

A method of manufacturing a gas barrier film includes depositing an atomic layer deposition film on a surface of a plastic substrate to form a gas barrier laminate, using atomic layer deposition; depositing a curable resin layer on a support from which the layer is peelable, to form an overcoat laminate; laminating the overcoat laminate to the gas barrier laminate, with the atomic layer deposition film and the curable resin layer facing each other, and transferring the curable resin layer onto the atomic layer deposition film; curing the curable resin layer through application of heat or an active energy beam; and releasing the curable resin layer from the support.

A modified collagen fiber preparation method and application are provided. The modified collagen fiber is prepared by modifying a collagen fiber with a plant tannin; and a method of the preparation includes: mixing the plant tannin with the collagen fiber in a liquid environment with a pH of 5 to 8 to allow a reaction, and washing and drying a product. In the present disclosure, a plant tannin rich in phenolic hydroxyl can be combined with a collagen fiber in various ways such as multi-point hydrogen bonding and hydrophobic bonding, such that the plant tannin structure is introduced into a natural multi-layer micro/nano-structure of the collagen fiber; and due to a large number of phenolic hydroxyl structures in the plant tannin, the collagen fiber introduced with the plant tannin structure shows improved compatibility with a waterborne resin, and can produce strong hydrogen bonding with polar groups in the waterborne resin.
