Document Type and Number:

Japanese Patent JPH06100687

Kind Code:

B2

Abstract:

There is proposed a bulb which is coated with an optical interference film consisting of alternately formed thin titanium oxide layers and metal oxide layers of a lower refractive index than that of titanium oxide layers. The characteristics of the bulb reside in the formation of each titanium oxide layer which is formed by thermal decomposition of a mixture consisting of 5 to 50 parts by weight of Ti(OR)4 and 95 to 50 parts by weight of polymerized Ti(OR)4, where R are C1 to C18 alkyl group, -OCOR' (R' is C1 to C18 alkyl group or -X radical which is capable of forming a chelate ring with titanium.
