The technical scheme for realizing the objective of the invention is as follows: an ultraviolet-cured transparent finishing coat with high colouring capacity for carpentry is composed of the following ingredients in parts by weight: 15-25 parts of urethane acrylate, 10-15 parts of epoxy acrylate, 5-10 parts of tripropylene glycol diacrylate, 5-10 parts of trimethylolpropane triacrylate, 5-15 parts of pentaerythritol triacrylate, 5-10 parts of a photoinitiator, 5-10 parts of active amine, 0.5-1.0 part of a dispersant, 0.5-1.0 part of a defoamer, 0.5-1.0 part of a leveller, 3-5 parts of wear-resistant powder, 3-5 parts of matt powder and 10-20 parts of an oily dye. The high-concentration oily dye is used in the ultraviolet-cured transparent finishing coat disclosed by the invention as a breakthrough, meanwhile, the dosage of active amine is increased in a formula, thus greatly solving the problem of achieving the high colouring capacity in one step, ensuring the adhesion force of the finishing coat, achieving the purpose of curing a coating film, and increasing the production efficiency.
