Summary:To provide photoactive compounds, photoresist compositions including the same, and pattern formation methods.SOLUTION: There is provided a photoactive compound including an organic cation; and an anion represented by Formula (1): wherein X is an organic group; Y1 and Y2 are each independently a non-hydrogen substituent; Y1 and Y2 together form a ring; Z2 is hydrogen, halogen, C1-30 alkyl, C3-30 cycloalkyl, C3-30 heterocycloalkyl, C6-50 aryl, C7-50 arylalkyl, C7-50 alkylaryl, C6-50 aryloxy, C3-30 heteroaryl, C4-30 alkylheteroaryl, C4-30 heteroarylalkyl, or C3-30 heteroaryloxy; Z2 further comprises one or more divalent linking groups as part of its structure; Z2 and one of Y1 or Y2 together form a ring; X and Z2 together form a ring; and X and one of Y1 or Y2 together form a ring.SELECTED DRAWING: None 【課題】光活性化合物、それを含むフォトレジスト組成物及びパターン形成方法の提供。【解決手段】有機カチオンと、下記式(1)で表されるアニオンとを含む光活性化合物。JPEG2024012132000037.jpg30170(Xは有機基であり;Y1及びY2は、独立して、水素ではない置換基であり;Y1とY2は、一緒に環を形成し;Z2は、水素、ハロゲン、C1~30アルキル、C3~30シクロアルキル、C3~30ヘテロシクロアルキル、C6~50アリール、C7~50アリールアルキル、C7~50アルキルアリール、C6~50アリールオキシ、C3~30ヘテロアリール、C4~30アルキルヘテロアリール、C4~30ヘテロアリールアルキル、又はC3~30ヘテロアリールオキシであり;Z2は、その構造の一部として1つ以上の二価連結基を更に含み;Z2とY1又はY2のうちの一方は、一緒に環を形成し;XとZ2は、一緒に環を形成し;XとY1又はY2のうちの一方は、一緒に環を形成する)【選択図】なし
