    abstract = {Oligolactide diols (OL-OHs) were synthesized by ring opening reaction of L-lactide with
1,6-hexanediol (HD) at 160°C for 3 h. The amount of HD was varied in order to obtain low molecular
weight OL-OHs. An Oligolactide Acrylate (OL-A) was then synthesized by functionalizing an OL-OH with
acrylic acid at 130&deg;C for 16 h. OL-OHs and the OL-A were characterized by <sup>1</sup>H-NMR, FTIR and GPC. The
viscosities of OL-OHs were measured by Brookfield viscometer. <sup>1</sup>H-NMR and FTIR results confirmed
that OL-OHs were synthesized successfully from lactide and HD as starting materials. It was found that an
increase in the HD amount led to lower molecular weight OL-OHs having lower viscosity. The <sup>1</sup>H-NMR and
FTIR results of the OL-A indicated that the OL-OH was functionalized with acrylic acid. A screen printing ink
was formulated from the OL-A. Cured ink film achieved by UV curing was characterized by FTIR. In addition,
adhesion of the obtained OL-A-based ink on various substrates was comparable with an ink made from
commercial polyester acrylate.}
