Curable composition, and cured coating, article, and method for forming coating using the same

A curable composition consisting of:

• a component (A) that is a polysiloxazane compound having a weight-average molecular weight of 3,000 to 10,000 and a number-average molecular weight of 2,000 to 8,000;
• a component (B) that is a silicone compound having a hydroxy group, wherein
• the component (A) contains constituent units a to d represented by the formula (1), and a mole ratio between each of the constituent units a:b:c:d is 5 to 15:1 to 3:6 to 10:0.5 to 1.5:
• in the formula (1), R1 represents an unsubstituted monovalent alkyl group having 3 to 10 carbon atoms, and R2 and R3 each independently represent an unsubstituted monovalent alkyl group having 1 to 6 carbon atoms;
• and m is 0 or 1, and n is an integer of 30 to 100;
• a component (C) that is a catalyst;
• a component (D) that is an organic solvent;
• and
• optionally at least one selected from the group consisting of an aging inhibitor, a rust preventing agent, an antifungal agent, a colorant, a surfactant, a rheology regulating agent, an ultraviolet absorbent, a fluorescent agent, a polishing agent, a perfume agent, and a filler.
