alkenes, thus steering their reactivity toward olefin crossmetathesis. Efficient functionalization has been observed for a range of coupling partners as a proof of concept for the use of olefin metathesis to graft small and larger molecules to polyethers for drug delivery. This approach also paves the way for the use of olefin crossmetathesis as an efficient method to functionalize a wide variety of polymers

Disclosed herein is a colored photosensitive resin composition including a copolymer, an epoxy resin compound or a compound derived therefrom, a polymerizable compound, a photoinitiator, and a colorant, wherein the photoinitiator includes an oxime compound and a triazine compound. The composition, when formed into a cured film, may facilitate the fabrication of necessary height difference and satisfy the requirements of sensitivity and an exposure margin for light shielding spacers, and, thus, is useful as a material for manufacturing a light shielding spacer such as a black column spacer used in various electronic parts including the panels of an LCD and an OLED display.

The invention relates to a monoethylenically unsaturated monomer of formula (I), and to the use thereof for producing a polymer. The invention also relates to the polymer obtained by polymerising said monomer, and to the use thereof in a composition for producing coatings.
A conventional silsesquioxane derivative has the problems that the functional groups are restricted and the chemical structure is not readily controlled and that it is expensive. The present inventors have developed a process for producing a silsesquioxane derivative at a high yield by a simple process in order to solve such problems. The novel silsesquioxane derivative according to the present invention is controlled in a structure thereof and has a functional group, which is excellent in reactivity with a target compound, to be modified. The present invention relates to a production process for a silsesquioxane derivative represented by Formula (2), characterized by using a silicon compound represented by Formula (1). In Formula (1) and Formula (2), R is a group selected from hydrogen, alkyl, aryl and arylalkyl; M is a monovalent alkaline metal atom; at least one of Y is a group represented by Formula (3), and the remainder of Y is hydrogen; R
1
and R
2
in Formula (3) represent the same group as defined for R; and Z is a functional group or a group having a functional group.
