Abstract: A method of producing a polymerizable composition including mixing a photochromic compound with one or more polymerizable compounds using an ultrasonic homogenizer.

Abstract: The photochromic compound is represented by the following general formula (1): wherein, X denotes an oxygen atom or a nitrogen atom unsubstituted or substituted by a substituent selected from the following Y1 group: Y1 group: —R1, -A1(B1)l(A2)m(B2)nR2, -A3A4, -A5R3 R1 denotes a cyano group or the like, R2 denotes an alkyl group or the like, R3 denotes a halogen atom or the like, A1, A2, A3, and A5 each independently denote an alkylene group or the like, A4 denotes a naphthyl group which may be substituted, B1 and B2 each independently denote any one of the divalent groups selected from the following group: l, m, and n are each independently 0 or 1, provided that n is 0 if m is 0, Y2 denotes a hydrogen atom or the like, R denotes a hydrogen atom or the like, denotes a norbornylidene group or the like.

Abstract: The present invention is to enable avoidance of a reduction in external appearance quality, and stable driving, and prevent diffracted light from being discerned by avoiding a reduction in transmittance and a deterioration in liquid crystal alignment. A light control film is provided with: a first laminate in which an alignment layer is provided; a second laminate in which an alignment layer is provided; a liquid crystal layer which is sandwiched between the first and second laminates and contains liquid crystal molecules; a spacer disposed in the liquid crystal layer to hold the thickness of the liquid crystal layer; and electrodes provided in the first laminate and/or the second laminate, and controls transmitted light by controlling the alignment of the liquid crystal molecules driven by the electrodes. The proportion of an area occupied by the spacer per unit area in a light controllable-region of the liquid crystal layer is 0.1-10%.
