Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a covering material capable of exhibiting excellent ultraviolet ray shielding performance under high temperature for a long time by laminating in order an adhesive layer made of an adhesive composition containing adhesive resin and an ultraviolet ray absorbing copolymer comprising at least one reaction type ultraviolet ray absorber and an unsaturated monomer, and a releasing agent on the one side of a resin film. SOLUTION: A reactive ultraviolet ray absorber is selected from a benzotriazole compound represented by formula I, a benzophenone compound represented by formula II, and a triazine compound represented by formula III. Methyl methacrylate is used as an unsaturated monomer. A copolymer has low transpiration property and crystallinity, and high heat resistance, and a fluorescent lamp covering material capable of using at 100 deg.C or higher for a long time is obtained. In formulas, R1 shows H, a halogen, a 1-8C alkyl group, 1-4C alkoxy group, a cyano group, or a nitro group; R2 shows a 1-12C alkylene group; R3 shows H, a 1-8C alkyl group; R4 shows H, a methyl group; R5 shows H, a hydroxyl group; R6 shows H, a 1-6C alkoxy group; R7 shows H, a 1-10C alkyl group, a 1-10C alkoxy group.
