Abstract: A radiation-curable ink jet composition includes a polymerizable compound component including a monofunctional monomer component and a multifunctional monomer component, a photopolymerization initiator, and titanium oxide as a white color material. The content of the monofunctional monomer component is 90 mass % or more based on the total amount of the polymerizable compound component, and the weighted average of the glass transition temperatures of homopolymers of the respective polymerizable compounds is 48° C. or more when the mass ratios of the contents of the respective polymerizable compounds are weighted.

Abstract: A rheology control agent for a curable composition may include: a diamide compound (A) and/or a hydrogenated castor oil (A?), the diamide compound (A) being obtained by condensation reaction between a diamine component (A1) and a monocarboxylic acid component (A2); and a polyamide compound (B) obtained by polycondensation of an amine component (B1) and a carboxylic acid component (B2). The diamine component (A1) may be selected from the group consisting of diamines with 2 to 12 carbon atoms. The monocarboxylic acid component (A2) may be selected from the group consisting of hydrogenated castor oil fatty acids and linear saturated fatty acids. The polyamide compound (B) may have a weight-average molecular weight from 2,000 to 21,000. A cured product of the curable composition may be used for a sealant or an adhesive.

Abstract: A rheology control agent for a curable composition includes: a diamide compound (A) and/or a hydrogenated castor oil (A?), the diamide compound (A) being obtained by condensation reaction between a diamine component (A1) and a monocarboxylic acid component (A2); and a polyamide compound (B) obtained by polycondensation of an amine component (B1) and a carboxylic acid component (B2). The amine component (B1) contains at least one amine selected from the group consisting of a diamine and a triamine having 2 to 54 carbon atoms. The carboxylic acid component (B2) contains at least one carboxylic acid selected from the group consisting of a dicarboxylic acid and a tricarboxylic acid having 4 to 54 carbon atoms. The polyamide compound (B) is obtained by polycondensation of at least one of the amine component (B1) and the carboxylic acid component (B2) containing polymerized fatty acids.

Abstract: An example system causes a computer of an information processing device including a restriction unit for restricting use of functions and a handwritten input receiving unit to carry out functions of requesting an input of a handwritten signature, sending, to a server, a result of a handwritten input which has been input in response to the request of the signature input, and receiving the input of authorization information which has been issued by the server that has received the handwritten input result and which shows that the use of the functions is authorized, and moreover cancelling the restriction by the restriction unit when the input of the authorization information is received.
