- heat and active energy ray-curable resin compositions contain low molecular weight components and can be viscous and fluid. However, when the heat and active energy ray-curable resin composition is heated, the resulting thermal reactant becomes tack-free because the low molecular weight component is crosslinked to have a high molecular weight.

That is, from the viewpoint of curability upon irradiation with active energy rays, the (meth) acrylic equivalent is preferably from 100 to 300 g Or 150 to 300 g Z eq. If the (meth) acrylic equivalent is larger than 300 geq, the abrasion resistance after irradiation with active energy rays is insufficient, and it is difficult to obtain a material having a molecular weight less than 100 gZeq.

- R is each independently a hydrogen atom or an alkyl group having 1 to 10 carbon atoms
- n is each independently an integer of 4 to 8
- m is each independently 1 to 20 It is an integer.
- one benzotriazolephenol becomes a bulky substituent of the hydroxyl group of the other benzotriazolephenol, and therefore plays an important role in ultraviolet absorption by reacting with a crosslinking agent. Does not lose phenolic hydroxyl groups. Further, since the molecular weight is large, the concentration does not decrease due to bleed out from the surface of the protective layer. In other words, it is easy to impart long-term weather resistance, and it is not localized at the interface with the adhesive layer and does not hinder the adhesiveness.
- the ultraviolet absorber of the present invention has a highly reactive hydroxyl group at the terminal of the long-chain polyester group, and is bonded to the polymer via a polyfunctional isocyanate which is one of the active ingredients.

- the polyfunctional isocyanate used in combination with the polymer in the present invention is not particularly limited, and various known polyfunctional isocyanates can be used.
- a prepolymer obtained by reacting a polyhydric alcohol with the above diisocyanate can be used.
- the reason why the polyfunctional isocyanate is used in combination with the polymer is that when the pattern layer 3 and the adhesive layer 4 are laminated on the protective layer 2, the adhesiveness of the protective layer 2 before irradiation with active energy rays is kept low, and The purpose is to satisfy to some extent the resistance to the solvent contained in the ink for forming the picture layer 3 and the adhesive layer 4. That is, a hydroxyl group contained in a polymer is reacted with an isocyanate group of a polyfunctional isocyanate to form a thermally crosslinked resin, thereby not providing the above performance.
- thermo-crosslinked resin polyurethane
- the thermally crosslinked resin has a network structure over the entire resin.
- the thermally crosslinked resin has a theoretically infinite molecular weight. Therefore, the protective layer made of the thermo-crosslinking resin is non-flowable and non-adhesive.

- the protective layer 2 becomes a heat-crosslinkable resin of the heat and active energy ray-curable resin composition.
- This thermally crosslinked resin is Since it is in a state of free contact, it becomes easy to print another layer on the protective layer 2 and wind up the transfer material 6.
- the protective layer 2 can adapt to the curved surface of the molded product, and has such flexibility as not to cause cracks.
- the crosslinking reaction by heating is easier to control than the crosslinking reaction by active energy ray irradiation. Therefore, the degree to which the protective layer 2 is crosslinked can be appropriately determined according to the type of the heat and active energy linear curable resin composition used, the curvature of the molded article, and the like.
