The present invention relates to a novel diamine compound, wherein two substituents R and R′ are introduced asymmetrically, and a polymer thereof. The polymer may have excellent solubility in the organic solvent and allows for easy processibility after imidization, thus giving proper film maintaining superior properties, such as thermal, mechanical, and optical properties for applications in electrical, electronic, or optical materials.
The present invention provides a novel diamine and a novel acid anhydride which are applicable for a polyimide and includes a cinnamoyl group or a derived cinnamoyl group. The novel diamines and acid anhydrides have photo-reactivity and heat-reactivity inherent to the cinnamoyl group.
A polyimide polymer that includes the reaction product of: (a) at least one diamine selected from the group consisting of a diamine of Structure (Ia) and a diamine of Structure (Ib),
(b) at least one diamine of Structure (II),
(c) at least one tetracarboxylic acid dianhydride, and optionally (d) at least one compound containing a first functional group reactive with an amine or an anhydride and at least one second functional group selected from the group consisting of a substituted or unsubstituted alkenyl group and a substituted or unsubstituted alkynyl group. Each variable in the above formulas is defined in the specification.

A photosensitive resin composition of the present invention contains a (A) soluble polyimide and a (b) (meth)acrylic compound, the (A) soluble polyimide being soluble in an organic solvent and being synthesized by using an acid dianhydride component and at least one of a diamine component containing a siloxane structure or an aromatic ring structure, and a diamine component having, in its structure, a hydroxyl group a carboxyl group or a carbonyl group, and the (B) (meth)acrylic compound having at least one carbon-carbon double bond, and preferably contains at least one of a (C) photo reaction initiator and a (D) fire retardant. With this arrangement, the photosensitive resin composition of the present invention is capable of having excellent properties. Especially, the photosensitive resin composition of the present invention is so excellently useful that it can be used for electronic parts and the like.
