A method of manufacturing a green body part comprises depositing a layer of a powder on a working surface; and selectively depositing a binder solution comprising a thermoplastic binder, a fluorescent material, and a binder medium into the layer of powder in a pattern representative of a structure of a layer of the green body part. The thermoplastic binder comprises one or more polymer strands dissolved in a solvent medium having an average molecular weight from greater than or equal to 7,000 g/mol to less than or equal to 100,000 g/mol. Binder solutions comprising fluorescent material and green body parts adhered together using the same are also disclosed.

The present invention provides a rubber composition for tires which provides a balanced improvement in ice performance, fuel economy, and abrasion resistance, and a pneumatic tire containing the rubber composition. The present invention relates to a rubber composition for tires containing a rubber component including at least 80% by mass in total of at least one of an isoprene-based rubber, a polybutadiene rubber, or a styrene-butadiene rubber, the rubber composition containing, per 100 parts by mass of the rubber component, 10 to 120 parts by mass of silica, 0.2 to 10 parts by mass of a tetrazine compound of formula (1), and 1 to 50 parts by mass of a low-molecular-weight diene polymer having a weight average molecular weight of 200,000 or less.
