<P>PROBLEM TO BE SOLVED: To provide a coating film which is dense and excellent in water resistance, chemical resistance, heat resistance and scratch resistance. <P>SOLUTION: A coating film 1 includes: a binder component containing at least one of a siloxane oligomer having a crosslinked structure and a siloxane oligomer of a linear type; and silica-based microparticles having a chain siloxane oligomer grafted on the surface thereof. In a spectrum obtained when analyzed by Raman spectroscopy, a relation I1/(I3+I4)≤0.011 is satisfied and also a relation I2/(I3+I4)≤0.15 is satisfied, where I1 denotes an integrated value of peak intensities existing in a first region of wave numbers 925-998 cm<SP POS="POST">-1</SP>, I2 denotes an integrated value of peak intensities existing in a second region of wave numbers 430-648 cm<SP POS="POST">-1</SP>, I3 denotes an integrated value of peak intensities existing in a third region of wave numbers 278-671, and I4 denotes an integrated value of peak intensities existing in a fourth area of wave numbers 671-1133. <P>COPYRIGHT: (C)2013,JPO&INPIT |
