  A photoactive compound is used in combination with a photosensitizer, represented by the following formula (1): A −[( J ) m −( X-Pro )] n (1) wherein A represents a hydrophobic unit comprising at least one kind of hydrophobic groups selected from a hydrocarbon group and a heterocyclic group, J represents a connecting group, X-Pro represents a hydrophilic group protected by a protective group Pro which is removable by light exposure, m represents 0 or 1, and n represents an integer of not less than 1. The protective group Pro may be removable by light exposure in association with the photosensitizer (especially, a photo acid generator), or may be a hydrophobic protective group. The hydrophilic group may be a hydroxyl group or a carboxyl group. The photoactive compound has high sensitivity to a light source of short wavelength beams, for resist application, therefore, the photoactive compound is advantageously used for forming a pattern with high resolution.

  Disclosed is a fluorine-containing polymer obtained by polymerizing a 1,6-diene-type ether compound represented by formula [1] and, for example, a (meth)acrylic acid compound represented by formula [2]. The fluorine-containing polymer shows high transparency, has a high glass transition point, and is soluble in a solvent and therefore has moldability.
