The object of the present invention is to provide a method for forming a hard coat layer comprising the following steps:
(A) a step of coating a composition for forming a hard coat layer comprising:
a) an organosilicon compound represented by formula (I) and/or its condensate
RnSiX4-n (I)
(wherein R represents an organic group in which a carbon atom is directly bound to Si in the formula, and X represents a hydroxyl group or hydrolysable group; n represents 1 or 2; and when n is 2, R may be the same or different, and when (4 - n) is 2 or more, X may be the same or different),
b) a ultraviolet ray curable-compound, and
c) a silanol condensation catalyst;
(B) a step of semi-curing the composition for forming a hard coat layer with heat and/or active energy ray;
(C) a step of conferring a desired shape; and
(D) a step of curing completely by irradiating active energy ray.
