Abstract: The resin composition of the present disclosure contains a fluorene derivative represented by the following formula (1) and a polyamide-series resin: Wherein R1 represents a substituent, k denotes an integer of 0 to 8, R2a, R2b, R2c, and R2d each represent a hydrogen atom or a substituent, R3a and R3b each represent a hydrogen atom or a substituent, and X1a and X1b each represent a group defined in the following formula (X1): wherein R4 and R5 each represent a hydrogen atom or a hydrocarbon group; or R4 and R5 bend together to form a heterocyclic ring containing the nitrogen atom adjacent to R4 and R5. The resin composition has an excellent fluidity.

Abstract: Provided are a retardation film that has a high heat resistance, has excellent formability and handleability even in a single-layer structure, has a negative thickness-direction retardation Rth value, and is suitable as a negative A-plate or a positive C-plate and a method for producing the film. The retardation film is formed of a stretched film of a polyester resin, contains a unit (A1) represented by the formula (1) as a diol unit (A) and a unit (B1) represented by the formula (2a) or (2b) as a dicarboxylic acid unit (B), and is a negative A-plate or a positive C-plate. In the formulae, Z1 and Z2 represent an aromatic hydrocarbon ring, R1, R2a, R2b, R3a and R3b represent a substituent, k, p1 and p2 denotes an integer of 0 to 8, q denotes an integer of 0 to 4, m1, m2, n1 and n2 denotes an integer of not less than 0, A1a and A1b represents an alkylene group, and A2a, A2b and A3 represents a divalent hydrocarbon group.

Abstract: There are provided an antifog property evaluating apparatus and an antifog property evaluating method capable of quantitatively and objectively evaluating an antifog property in a more realistic situation. The antifog property evaluating apparatus includes: fogging generation devices configured to generate the fogging of a surface of a sample; an object disposed at a position different from that of the sample; an imaging device configured to image the object via the sample; and an evaluation device configured to evaluate the antifog property of the sample on the basis of object images acquired by imaging the object.
