Abstract
A curable resin composition having high transparency in the UV region, UV resistance and heat resistance. The curable resin composition includes an alkoxy oligomer represented by Formula 1 of (RRRSiO)(RRSiO)(RSiO)(SiO)and a curing catalyst. The curing catalyst is phosphoric acid present in an amount of 3-30 parts by weight based on 100 parts by weight of the alkoxy oligomer, or alkoxide of at least one metal selected from the group consisting of B, Al, P, Sc, Ga, Y, Zr, Nb, In, Sn, La, Gd, Dy, Yb, Hf, Ta and W, present in an amount of 0.5-20 parts by weight based on 100 parts by weight of the alkoxy oligomer. Each of R, R, R, R, Rand Rindependently represents the same or a different organic group, w, x, y and z are 0 or positive numbers satisfying the relationship of w+x+y+z=1, and the atomic ratio of O/Si is 2.3-3.5.
