    Abstract: PROBLEM TO BE SOLVED: To obtain a new photochromic material, comprising a specific spirobenzoxazine compound, normally colorless and capable of developing a color by irradiation with ultraviolet rays, reversibly carrying out the development of the color and decolorization and manifesting hues of rich color development species, a high temperature for enabling the color development and good fatigue resistance. SOLUTION: This photochromic material is a compound represented by formula I [R is a 1-20C (substituted) alkyl (Ra ), a 7-20C (substituted) aralkyl (Rh ) or a 6-19C (substituted) aryl (Rc ); R is OH, a (substituted) amino, a 1-20C alkoxy, etc.; R and R are each R and R and R together may form a 3-10C (substituted) cycloalkyl including the carbon at the 3'-position; R to R are each H, Ra or Rb ; (1) is 1-4] and a compound represented by formula II is exemplified. The compound represented by formula I is obtained by adding a compound represented by formula III to a quaternizing agent which is a compound represented by the formula R -X (X is an anionically eliminable group), a basic substance and a compound represented by formula IV in an optional order and carrying out a reaction.

    Abstract: PROBLEM TO BE SOLVED: To provide a secondary battery in which reduction in a high output capacity/low output capacity is lessened by limiting a relationship between conductivity and viscosity of a non-aqueous electrolytic solution in a nonaqueous secondary battery. SOLUTION: In a secondary battery provided with a positive electrode, a negative electrode, and a nonaqueous electrolytic solution containing LiBF4 as electrolyte, a ratio (p)=σ/η of the conductivity σ (10 S/cm) to the viscosity η(cps) of the nonaqueous electrolytic solution is 0.5 or more. A mixture of a high dielectric constant solvent and a low viscosity solvent is desirable for a solvent constituent of the nonaqueous electrolytic solution. A combination of cyclic carbonate and chain carbonate is especially suitable, as it increase a high output capacity.

    Abstract: PURPOSE: To obtain a coating composition useful as a coating for precoated steel plates and improved in press processability, especially in corrosion resistance, bending resistance, adhesiveness, mold scoring, wet-on-wet coating, etc., by mixing a specific polysulfide modified epoxy resin with a curing agent in a specific ratio. CONSTITUTION: This coating composition comprises (A) a polysulfide modified epoxy resin [e.g. a resin expressed by formula I (R and R are each an organic group; R and R are each an epoxy prepolymer residue having >=2 epoxy groups in a molecule; X and Y are each S, O or NH; (a) is 0-5, when (a)=0, at least one of X or Y is S; (b) is 1-50)] and (B) a melamine-based resin of formula II [R to R are each H, a group of the formula: CH2 OR (R is a 1-4C alkyl)] as a curing agent. The weight ratio of the component B to the component A is 0.05-0.3.
