PROBLEM TO BE SOLVED : To provide a synthetically excellent re-emulsifying type powdery resin for planting, excellent in a low-temperature film-forming property and sticking tendency, preferably further excellent in germination of seeds and water resistance.
SOLUTION : The re-emulsifying type powder resin for planting comprises a powdery resin obtained by removing a medium from an emulsion (A) of a vinyl-based synthetic resin having ≥20°C glass transition point and a liquid film-forming auxiliary (B) having 160-280°C boiling point and has ≤5°C lowest film-forming temperature. The resin can maintain the lowest film-forming temperature in a low value while improving the sticking tendency. The low-temperature film-forming property and the sticking tendency are further improved by mixing the emulsion (A) with the film-forming auxiliary (B) and then spray-drying the mixture to produce the powdery resin.
