Title:

感光性組成物、感光性フィルム、永久パターン形成方法、及びプリント基板

Document Type and Number:

Japanese Patent JP4657955

Kind Code:

B2

Abstract:

To provide a photosensitive composition which excels in storage stability, suppresses color failure of a binder resin, and is capable of efficiently forming a high-definition permanent pattern, a photosensitive film, a permanent pattern forming method using the photosensitive composition, and a printed circuit board on which a permanent pattern is formed by the permanent pattern forming method.

The photosensitive composition contains a binder, a polymerizable compound, a photopolymerization initiator, a heat crosslinking agent and a catalyst, wherein the binder contains a high molecular compound having at least one structural unit represented by one of formulae (I)-(III) and the remaining amount of the catalyst is ≤0.4 mass%. In the formulae (I)-(III), R1-R12each independently represent either H or a monovalent organic group; X, Y and Z each independently represent an organic linking group; and L represents an organic cyclic group.
