Title
(EN) THREE-DIMENSIONAL OBJECT PRECURSOR TREATMENT AGENT COMPOSITION
(FR) COMPOSITION D'AGENT DE TRAITEMENT DE PRÉCURSEUR D'OBJET TRIDIMENSIONNEL
(JA) 三次元物体前駆体処理剤組成物
Abstract
(EN)
A three-dimensional object precursor treatment agent composition according to the present invention is for removing a support material from a three-dimensional object precursor which comprises: a three-dimensional object; and a support material including a (meth)acrylic acid-based copolymer which has, as monomer units, a hydrophilic monomer and a hydrophobic monomer. This three-dimensional object precursor treatment agent composition contains a compound (component A) represented by formula (I), and water (component B), and has a pH of at least 12. According to the three-dimensional object precursor treatment agent composition according to the present invention, it is possible to remove a support material including a (meth)acrylic acid-based copolymer more quickly than before. (In formula (I), R1, R2, and R3 are each independently at least one selected from an alkyl group having 1-8 carbon atoms, and a phenyl group, and R4 represents an alkyl group having 1-8 carbon atoms, a hydroxyalkyl group having 1-8 carbon atoms, a phenyl group, or a benzyl group.)

L'invention concerne une composition d'agent de traitement de précurseur d'objet tridimensionnel, servant à éliminer un matériau de support d'un précurseur d'objet tridimensionnel comprenant : un objet tridimensionnel ; et un matériau de support contenant un copolymère à base d'acide (méth)acrylique comprenant, comme unités monomères, un monomère hydrophile et un monomère hydrophobe. La composition d'agent de traitement de précurseur d'objet tridimensionnel selon l'invention contient un composé (composant A) représenté par la formule (I) et de l'eau (composant B), et présente un pH d'au moins 12. La composition selon l'invention permet d'éliminer un matériau de support contenant un copolymère à base d'acide (méth)acrylique plus rapidement qu'auparavant. (Dans la formule (I), R1, R2 et R3 représentent chacun indépendamment au moins un élément sélectionné dans un groupe alkyle contenant de 1 à 8 atomes de carbone, et un groupe phényle, et R4 représente un groupe alkyle contenant de 1 à 8 atomes de carbone, un groupe hydroxyalkyle contenant de 1 à 8 atomes de carbone, un groupe phényle ou un groupe benzyle.)
