  4-dinitrophenyl X-substituted cinnamates (1a, 1c, and 1e) with amines are curved with a decreasing βnuc value from 0.65 to 0.3−0.4. The reactions of Y-substituted phenyl cinnamates (3a−g) with morpholine also result in a curved Brønsted plot, while the corresponding reactions of Y-substituted phenyl benzoates (4a−e) exhibit a linear Brønsted plot. It has been concluded that the curved Brønsted plots found

  A first object of the present invention is to provide a method for producing a cholesteric liquid crystal layer, which can produce a cholesteric liquid crystal layer whose reflection surface is not parallel to the substrate surface by a simple method. A second object of the present invention is to provide a cholesteric liquid crystal layer, and an optically anisotropic body and a reflective layer, each of which includes the cholesteric liquid crystal layer. A third object of the present invention is to provide a liquid crystal composition capable of forming the cholesteric liquid crystal layer. A fourth object of the present invention is to provide a cured product, an optically anisotropic body, and a reflective layer, each of which is formed of the liquid crystal composition. The method for producing a cholesteric liquid crystal layer of the present invention includes a step 1 of forming a composition layer satisfying the following condition 1, the following condition 2, or the following condition 3 on a substrate, using a liquid crystal composition including a liquid crystal compound; and a step 2 of subjecting the composition layer to a treatment for cholesterically aligning the liquid crystal compound in the composition layer to form a cholesteric liquid crystal layer. Condition 1: at least a part of the liquid crystal compound in the composition layer is tilt-aligned with respect to a substrate surface Condition 2: the liquid crystal compound is aligned such that a tilt angle of the liquid crystal compound in the composition layer continuously changes along a thickness direction; Condition 3: at least a part of the liquid crystal compound in the composition layer is vertically aligned with respect to the substrate surface.
