To obtain a phenolic novolak-type vinyl ether containing phenolic novolak-type vinyl ether compounds of tetra-nuclear form and binuclear form at specific ratios and useful as a composition for ink, etc., giving a cured material exhibiting low skin stimulation and excellent adhesion.
The objective compound contains ≥30 wt.% of a tetranuclear phenolic novolak-type vinyl ether compound expressed by formula I {[R is a vinyl ether group of {(R1)p-O-}q-CH=CH2 (R1 is a 1-10C alkylene; (p) is 1-10; (q) is 0-10) or H]; the ratio of H atom/vinyl ether group is 0/100 to 70/30 (molar ratio) as an average over the whole molecule of formula I} and ≤15 wt.% of a binuclear phenolic novolak-type vinyl ether compound of formula II. The objective compound can be produced by reacting a phenolic novolak with a haloalkylenoxy vinyl compound of formula III (X is a halogen) in the presence of a basic compound.
