RADIATION CURABLE COMPOSITION, OPTICAL WAVEGUIDE AND METHOD OF FORMING THE OPTICAL WAVEGUIDE
A radiation curable composition which comprises (A) a hydrolyzate of a hydrolyzable silane compound represented by the general formula (1): (R1~)~p(R2~)~qSi(X)~4-p-q wherein R1 ~is a non-hydrolyzable organic group having 1 to 12 carbon atoms and containing a fluorine atom, R2 ~is a non- hydrolyzable...

Summary: | A radiation curable composition which comprises (A) a hydrolyzate of a hydrolyzable silane compound represented by the general formula (1): (R1~)~p(R2~)~qSi(X)~4-p-q wherein R1 ~is a non-hydrolyzable organic group having 1 to 12 carbon atoms and containing a fluorine atom, R2 ~is a non- hydrolyzable organic group having 1 to 12 carbon atoms (except the one containing a fluorine atom), X is a hydrolyzable group, p is an integer of 1 or 2, and q is an integer of 0 or 1, or a condensate thereof, and (B) an age nt generating an acid by the irradiation with a light, and contains a silanol ( Si- OH) group in an amount of 0.1 to 0.5 relative to the total amount of bonding groups on the Si~s therein. The composition allows the formation of an optic al wave guide which is reduced in a waveguide loss with respect to lights havin g wave lengths of a wide range from a visible region to a near infrared region , and also is excellent in the resistance to cracking, characteristics of patterning by irradiation with a radiation, and the like. |
