An odor-resistant film-forming composition capable of preventing the migration and lingering of odors onto substrates, which contains a first type of silicon compound with an amino group and a plurality of hydrolyzable groups in the molecule and a second type of silicon compound without an amino group but with a plurality of hydrolyzable groups in the molecule, wherein at least one of the first type of silicon compound and second type of silicon compound includes a silicon compound which has 3 or more hydrolyzable groups in the molecule. The proportion of Weight A of the silicon compound of either the first type of silicon compound or second type of silicon compound having two hydrolyzable groups in the molecule comprises 20-90% of the total of the Weight A and Weight B of the silicon compound(s) having 3 or more hydrolyzable groups in the molecule, the proportion of Weight C of the first type of silicon compound is 20-90% of the total of the Weight C and Weight D of the second type of silicon compound; and the second type of silicon compound includes at least one type selected from a group consisting of specified compounds.

Composition formant une pellicule qui résiste aux odeurs; elle empêche la migration et la persistance d'odeurs sur divers substrats. La composition renferme un premier type de composé silicié, dont la molécule porte un groupe amino et plusieurs groupes hydrolysables, et un second type de composé silicié, sans groupe amino, mais avec plusieurs groupes hydrolysables; au moins l'un des deux types de composés siliciés comprend un composé avec 3 groupes hydrolysables ou plus dans la molécule. La proportion de masse A de composé silicié de n'importe lequel des deux types de composés siliciés renfermant deux groupes hydrolysables dans la molécule représente 20 à 90 % du total de la masse A et de la masse B du ou des composés siliciés possédant 3 groupes hydrolysables ou plus dans la molécule; la proportion de masse C du premier type de composé silicié représente de 20 à 90 % du total de la masse C et de la masse D du second type de composés silicié; ce dernier type de composé renferme au moins un type choisi dans un groupe constitué de composés spécifiques.
